Answer:

125x^3 + 27/ 64

Step-by-step explanation :

This can be done in man ways. But I recommend solving what is inside the brackets first.

So add 5x/4 and 3/4, which gives 5x+3/4

Now, rewrite the term with simplified brackets

(5x+3/4)^3

Now we have to cube 5x+3/4

5x+3/4^3 = 125x^3 + 27/64

Hope this helps
