If x and y are integers, which of the following is equivalent to
A. (2x)^2y
B. 2^y(x^3-x^y)
C. (2x)^y[(2x)^2y-1]
D. (2x)^y(4x^y-1)
E. (2x)^y[(2x)^3-1]
---------------------
A is a monomial, so it's out.
---------------------
B. 2^y(x^3-x^y) = 2^y*x^3 - 2^y*x*2y That's not it
-----------------
C. (2x)^y[(2x)^2y-1] = (2x)^3y - (2x)^y That's it.
It's C
