Maths help with exponentials

Question

Evaluate

(z x^-1 y)^5 y^5

~~~~~~~~~~~~~~~~~~~~~~~ OVER

x^-4 z^-4

How would I evaluate this if X = 10, y = -3 and z = 3? I would like a step-by-step solution to help me fully understand it.

Answer 1

Numerator evaluates as (z*y*x^-1)^5 * y^5

further rewriting ((z^5*y^5)*y^5)/x^5

Denominator ((1/x^4)*(1/z^4))

Final Answer would be ((y^10)*(z^9))/x

as per your values it (3^19)/10
