The cube root of a number is a number that you multiply by itself three times to give the original number. for example, 4 is the cube root of 64 because 4 × 4 × 4 = 64. an irrational number is a decimal number that never ends and that can’t be represented with a fraction. the square root of 2 is an irrational number. The definition of square and cube roots. a square root74 of a number is a number that when multiplied by itself yields the original number. for example, 4 is a square root of 16, because 42 = 16. since (− 4)2 = 16, we can say that − 4 is a square root of 16 as well. every positive real number has two square roots, one positive and one negative. How to find square root and cube root. to find the square root of the number, we have to determine which number was squared to get the original number. for example, if we have to find the root of 16, then as we know, when we multiply 4 by 4, the result is 16. hence, √16 = 4. similarly, if we have to find the cube root of a number, say 64.

It will help to be familiar with the common cube roots like we did with the common square roots. some perfect cube roots: 1 x 1 x 1 = 1. 2 x 2 x 2 = 8. 3 x 3 x 3 = 27. 4 x 4 x 4 = 64. 5 x 5 x 5 = 125. 6 x 6 x 6 = 216. 7 x 7 x 7 = 343.
