Question

What is cube root? also whats square root? help?​

Answer 1

A cube root is an exponent of one-third. Square roots of negative numbers do not have real number roots since the product of any real number and itself is positive. Cube roots do exist for negative numbers since the product of three negatives is a negative.

Step-by-step explanation:

Finding the cube root of a number means determining a number that when multiplied by itself three times gives you your original number. For example, the cube root of 8 is 2 since 2 x 2 x 2 = 8. For example, the cube root of 8 is 2 since 2 x 2 x 2 = 8.

he square root of a number is a number that you can square to get it, that is, a number that you can multiply by itself to get the number. So, 2 is a square root of 4, because 2 x 2 = 4, and 3 is a square root of 9, because 3 x 2 = 9. (-2) x 2 is also 4 and (-3) x 2 is also 9.

Answer 2

a cube root of a number x is a number y such that y3 = x.

a square root of a number x is a number y such that y2 = x

For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16.
