Not all numbers or expressions have an exact square or cube root. If a number is NOT a perfect square or cube, you might be able to simplify it. Simplifying Radicals

2 Extract the square root or cube root of the factor that is a perfect cube or square. 1 Write the radicand as a product of two factors, where one of the factors is a perfect square or perfect cube. 3 The factors that are not perfect squares or cubes will remain as the radicand. To Simplify a Radical

Use a factor tree to see if there is a square or cube factor to extract.
