Worksheet Overview

When we find the cube of an algebraic term, we simply multiply it by itself and then by itself.

Thus the cube of 2a4 is  

2a4 x 2a4 x 2a4 = 8a12

 

The reverse of cubing is finding the cube root.

So  3√8a12 = 2a4

(i.e. we find the cube root of the number and divide the index by 3)
