When we find the cube of an algebraic term, we simply multiply it by itself and then by itself again.
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
This means that we find the cube root of the number and divide the index by 3.
Let's try some questions.
