What are Mathematical Roots?
A Square Root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 25 is 5, because 5 × 5 = 25.
A Cube Root is a number that when multiplied by itself three times gives the original number. For example, the cube root of 27 is 3, because 3 × 3 × 3 = 27.
