Answer:

(4x^3)(2x)^-4
Rewrite the equation
4x^3*2^-4 x^-4
Write in exponential form
2^2 x^3*2^-4 x^-4
2^-2 x^-1
Rewrite and change the power of -2 to a positive 2
1/2^2*1/x
1/4*1/x
1/4x

P.S the * represents multiplication, and in between some exponents I spaced them out, since I can’t write it properly on here without it looking like, for instance 2^2x^3 it’s suppose to be written together however it looks as if the exponent is 2x instead of being 2. You’d get the picture though.
