You've given us a formula, but not given us what we are supposed to be doing with it...

the expression needs to be simplified
I tried

Oh! Okay, well anything to the negative power is equal to the reciprocal to the same positive power. Therefore;

(x^-4*y^2/x^-2*y^-4)^-3
= (x^-2*y^-4/x^-4*y^2)^3

You can then multiply each exponent within the brackets by 3. And simplify your numerator and denominator from there...

Let me know if you still need a hand!
