Root (of a number) - math word definition - Math Open ReferenceThe root of a number x is another number, which when multiplied by itself a given number of times, equals x.
For example, the third root (also called the cube root) of 64 is 4, because if you multiply three fours together you get 64:
4 × 4 × 4 = 64
This would be written as The above would be spoken as "the third root of 64 is 4" or "the cube root of 64 is 4". The second root is usually called the "square root". The third root of a number is usually called the "cube root", After that, they are called the nth root, for example the 5th root, 7th root etc Sometimes there are two rootsFor every even-degree root (for example the 2nd, 4th, 6th ....) there are two roots. This is because multiplying two positive or two negative numbers both produce a positive result. For example, consider the square root of 9.
