Cube root of perfect cubes


The product of the same three factors is called a perfect cube.

For example,
1 is a perfect cube because 1=1x1x1=13
8 is a perfect cube because 8=2x2x2=23
27 is a perfect cube because 27=3x3x3=33
64 is a perfect cube because 64=4x4x4=43
...

The cube root of a number is the opposite (or inverse) of cubing a number.


    because 4x4x4=64

    because 5x5x5=125


To find the cube root of a fraction, reduce the numerator and the denominator to perfect cubes is possible.
