Question

Lets say we have (4xy^2)^ -1

what would happen? Do we multiply -1 and 2? or what? what would the final outcome be?

Answer 1

A^-1 = 1/A

So  (4xy^2)^ -1 = 1/(4xy^2)

Answer 2

(

4xy^2)^ -1 = 1/ (4xy^2)

anything to the power of -1 is its inverse so anything^-1 = 1/anything

Answer 3

(4xy^2)^ -1 = 1/ (4xy^2)
