the simplified expression is a^12 / 8b^33

For this case we must solve the following expression:


((a^(-2)*b^2)^(-3))/((a^2*b^(-10))^(-3))

By definition of power properties we have to:


(a^n)^m=a^(n*m)

Rewriting we have to:


(a^(-2*-3)*b^(2*-3))/(a^(2*-3)*b^(-10*-3))=\\(a^(6)*b^(-6))/(a^(-6)*b^(30))=

By definition we have to:


a^(-1)=(1)/(a^1)=(1)/(a)

So:


(a^6*a^6)/(b^6*b^(30))=

By definition of multiplication of powers of the same base, we place the same base and add the exponents:


(a^(12))/(b^(36))

Answer:


(a^(12))/(b^(36))
