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.

Finding horizontal asymptotes is very easy! Not all rational functions have horizontal asymptotes. the function must satisfy one of two conditions dependent upon the degree (highest exponent) of the numerator and denominator. If the degree of the numerator is equal to the degree of the denominator, then the horizontal asymptote is y= the ratio of the leading coefficients. If the degree of the denominator is greater than the degree of the numerator then y= 0. If the degree of the denominator i...

To find a vertical asymptote, you are trying to find values of x that produce 0 in the denominator but not in the numerator. If 0/0 occurs, that means you have a "hole" in the graph. A vertical asymptote is a place in the graph of infinite discontinuity, where the graph spikes off to positive or negative infinity. To find the vertical asymptote, set the denominator equal to zero and solve for x. Check that the values also do not give a zero in the nominator. If the values work, you have found...
