Question

Use the rules of exponents to evaluate and simplify the following expression. Type all without negative exponents.

(ab)-2 =

Answer 1

x 1/3 y 1/2

I'm not very mathematically inclined, but I saw this on a different website. So I could be wrong

Answer 2

For this case we have the following expression:
(ab) ^ - 2
Rewriting the expression we have:
(ab) ^ - 2 = 1 / (ab) ^ 2
Then, for power properties we have:
1 / (ab) ^ 2 = 1 / (a ^ 2b ^ 2)

Answer:
The simplified expression is:
1 / (a ^ 2b ^ 2)
