Answer:
To transform the given expression to the sum of cubes, calculate first the cube root of the terms. The cube root of the first term, 64x^6 is 4x^2 and that of the second term, 27 is 3.
Thus, the answer to this is (4x^2)^3 + 3^3
We must first open the parenthesis. We get 15*7+15y, or 105+15y. We can now add 12 to 105 which would be 117. Now we have -4-5y+117+15y. With this we can move the -4 to 117 which is 113 and the -5y to 15y which is 10y. So we got 113+10y as our answer.
Hope this helps. <3
Answer:
dang I'm sorry I thought I was right but the question you're asking is a different one but I will try to help you one the one you're on
-1 for the last one all of them involve 3 and the 1 isn’t 3 so it would be -1 hahaha
