WebbWhile square roots are probably the most common radical, you can also find the third root, the fifth root, the 10th root, or really any other nth root of a number. Just as the square root is a number that, when squared, gives the radicand, the cube root is a number that, when cubed, gives the radicand. Find the cube roots of the following ...
WebbTo simplify a cube root, first look for the largest perfect cube factor of the radicand. Then, apply the following property: Let a a and b b be real numbers. Then, \sqrt [3] {ab}=\sqrt [3] {a}\times \sqrt [3] {b}. 3 ab = 3 a× 3 b. Simplify \sqrt [3] {81}. 3 81.
