Read the question as:

8/125x^3 + 64y^6
=(2x/5)³+(2y²)³

You will need the standard identity:
a^3+b^3=(a+b)(a^2-ab+b^2)

Give it another try.

To simplify the expression 8/125x^3 + 64y^6, you can follow these steps:

Step 1: Simplify any numerical values.
In this case, 8/125 is already in its simplest form, so we can move on.

Step 2: Simplify any variables with the same base and combine their exponents.
In this case, we have x^3 and y^6. Since there are no other x or y terms to combine with, we can't simplify any further.

So, the simplified expression is 8/125x^3 + 64y^6.
