Simplify
(a^2 b^-2)^-3 * (a^-1 b^2)^-3

Answer 1

Because they have the same exponents you can ignore those.

Now you just have to multiply.

What is a^2(a^-1)(b^-2)(b^2) ? ?

Answer 2

When you are multiplying exponents, you just have to add them

a^(2-1)b^(-2+2)

All to the -3 power

Answer 3

where did the -3s go

Answer 4

so the answer is a^-3

Answer 5

Correct :)

Answer 6

thanks and can you help me on another one

Answer 7

(3xy^3)^-2 * (9y)^2

Answer 8

Multiply in the -2 and 2

3^-2(x^-2)(y^-6)(9^2)(y^2)

Answer 9

Then simplify:

(1/9)(x^-2)(y^-4)(81)

= 9x^(-2)(y^-4)
