Please explain how to solve it

This is the fraction 8x^3 all over 27y^6

On a keyboard, we can write it as (8x^3)/(27y^6)

===========================================================

Explanation:

The exponent tells you how many copies of the base to multiply with itself.

We'll have three copies of multiplied with itself due to the cube exponent on the outside.

So,

-------------------

Or another approach you could take is to cube each component of the fraction. The rule I'm referring to is

Applying that rule will lead to:

Either way you should get 8x^3 all over 27y^6 as one fraction.
