x^12/(64y^6)

Explanation:

Our expression is the same as

1/(4x^-4y^2)^3

4^3=color(blue)(64), (x^-4)^3=x^(-4*3)=color(blue)(x^(-12)), (y^2)^3-y^(2*3)=color(blue)(y^6)

With this in mind, we now have the following:

1/(64x^-12y^6)

We can make the negative exponent positive by bringing it to the numerator. We now have

x^12/(64y^6)

Hope this helps!
