This type of radical is commonly known as the square root. means of the most recent email address, if any, provided by such party to Varsity Tutors. Because these factors are perfect squares, we can easily take their square root out of the radical, which then gets multiplied by the coefficient already in front of the radical: After simplifying each radical, we're left with the same value of in each term, so we can now add all of our like terms together to completely simplify the expression: In order to solve this equation, we must see how many perfect cubes we can simplify in each radical. That is, the product of two radicals is the radical of the product. Even if you decide to say , it doesn't make statement III false. Rewrite showing the common factors of the numerator and denominator. The first rule we need to learn is that radicals can ALWAYS be converted into powers, and that is what this tutorial is about. After removing all common factors from the numerator and denominator, if the fraction is not a perfect power of the index, we simplify the numerator and denominator separately. We can rewrite the radical using these factors. It might help to think of (y 2) 3 as a group of three y 2 's, and (y 2) 3 = y 6 thanks to exponential Rule 3 from Encountering Expressions.
