Here we look at squaring expressions that involve radicals because people tend to make some common mistakes while solving such expressions. Take 5 times the square root of y quantity squared, the answer here is not 5y. Here's the reason, square means to multiply something with itself so the square of 5 root y would be 5 root y into 5 root y. So 5 x 5 is 25 and under root y into under root y equals just y so the answer will be 25y.

How to pick plants and trees at a nursery
This is an illustrative video on how to rationalize a denominator. Let us take an example of 1 over root 2. If we have to rationalize this denominator, we need to multiply it and divide it by root 2. You will get root 2 over 2. Similarly if you want to rationalize 4 root 6 over root 2, we have to multiply and divide it by root 2. We will get 4 root 12 over 2. That is equal to 2 root 12. In this way you can find rationalize the denominator easily.
A 45 45 90 triangle is a special right triangle because you can use short cuts to find leg length and hypotenuse length. This video solves two problems involving leg length and hypotenuse length.
Welcome back, my nascent hackers! We have spent a lot of time in previous tutorials focused on hacking the ubiquitous Windows systems, but the vast majority of "heavy iron" around the world are Linux or Unix systems. Linux and Unix dominate the world of Internet web servers with over 60% of the market. In addition, Linux and Unix servers are the operating system of choice for major international corporations (including almost all the major banks) throughout the world.
There's a new macOS vulnerability that hackers within physical reach of your computer can use to gain root access to your system and accounts. Just by using "root" as the username and a blank password on a privilege escalation prompt, someone can install malware on your computer, access hidden files, reset your passwords, and more. Root access gives them the ability to do anything they want.
In this video, we learn how to rationalize the denominator. This says that if there is a square root or any type of root, you need to get rid of them. Look at the examples given in the video to get an idea of what types of roots you will be removing and how to do it. To get rid of a square root, all you really have to do is to multiply the top and bottom by that same square root. Do this on all of your problems with a square root and they will be gone in just a matter of minutes!
This video shows you how to dice a yellow onion quickly and easily.
In this algebra video the instructor shows how to work with complex numbers. When you have a positive number under the square root, you can easily find its value by writing it in the form of product of numbers, and then solving. That is, to find the square root of a positive number, you can find another number which multiplied by itself gives the original number. This new number becomes the square root of the original number. But when you are asked to find out the square root of a negative nu...
Radicals are square roots which are not integers; the square roots of 2 or 3 are examples of radicals. The presenters show simple ways of how to add and subtract such radicals. They explain that by using the method of factoring, the addition or subtraction is made very easy. If the square root of 8, for instance, is in some addition sum, it can be factored into the square root of 4 times the square root 2. Since we know that the square root of 4 is 2 this can be simplified to be 2 times the s...
This video shows how to multiply similar radicals. The basics of doing this is to multiply the root of the radicals. For instance, if you have the cubed root of 14 multiplied by the cubed root of 3, you would only multiply the root numbers. Thus, your answer would be the cubed root of 42. The exercises in this video show a few basic examples, but they can help you down the road when completing more complex problems that involve multiplying similar radicals.
Michael Andrew, from Meals Americana, gives us some interesting tips on dicing an onion without tears.
Things you’ll need: Sharp kitchen knife Cutting board Onion Step 1 Leave the root side of the onion intact. Step 1 Leave the root side of the onion intact. Slice off the other end of the onion. Step 2 Remove the papery skin as well as the first layer of the onion. Cut the onion in half, and place one half on top of a cutting board with the side flat down. Step 3 Make a series of vertical slits in the onion from the root down, making sure not to cut through the root end. Leave about 1/2" at th...
Chord inversions are a great way to use the same series of notes in a chord to get different voicings. For the example in this video use a C-major triad, which contain the notes C, E, G. Playing these three notes in this pattern is called the root inversion. The first inversion is to use the root being C and put the note up one octave. Now the chord is played E, G, and C. The second inversion is two take the E and put that note up one octave. Now the pattern goes G, C, and E. These three inve...
When you need to compute the square root of a number you can do it by breaking it into perfect squares. When you can split the given number into small perfect squares you can cancel out the square root of the expression to the square of the perfect squares. You cannot always write the number inside the square root as a perfect square, but try to write this number as a product of a perfect square and another number. Now you can pull out the perfect square out of the radical and leave the remai...
In this video the tutor shows how to simplify a quadratic formula result. You can solve a quadratic equation using the quadratic formula. The first thing you have to do when given the quadratic equation is bring all the terms to one side so that you have a zero on the other side of the equals to sign. Now the formula to calculate the roots of the quadratic equation ax*x + bx + c = 0 is x = (-b + root of(b*b - 4*a*c) ) / 2 * a. The other root can be obtained by using the minus sign before the ...
While dividing the radicals, the numerator and the denominator must be combined into a single term, for example if we want to divide square root of 3 by square root of seven we need to combine the numerator and denominator into a single factor that is square root of 3/7, then we can divide 3/7 which is 0.4285, and square root of 0.4285 is 0.654 which is the final answer.
In this video, we learn how to rationalize a denominator that contains a surd. First, you need to rationalize the denominator by removing any square root sign. To do this, you will multiply the fraction but the flip of the denominator over itself, with the square root. Then, you will multiply the top by the bottom with the square root and this will remove it from the equation once you do the math to multiply it out. Once you're done, the number will be rationalized and you will have the answe...
In most macOS hacks, a non-root terminal is used to create a backdoor into the device. A lot of damage can be done as a low-privileged user, but it has its limitations. Think twice before granting a file permission to execute — an attacker might be able to convert your harmless scripts into persistent root backdoors.
The beta firmware for OnePlus devices lets you record calls from the stock Oxygen OS dialer, but this feature is never included in official updates. This is likely due to legal issues with recording calls in some jurisdictions, but thankfully, there's a way to get this feature without having to run beta software.
It just keeps getting harder to enjoy all of the benefits of root without sacrificing features. Thanks to SafetyNet, we've lost the ability to use Android Pay, Pokémon GO, and even Snapchat to an extent. But the most recent news on this front is perhaps worst of all: Netflix has already stopped showing up on the Play Store for rooted users, and soon, it may refuse to run even if you've sideloaded the app.
