How do you use the laws of exponents to simplify the expression #-(9^2 x^-2 y^2)^-1/(9^4 x^4 y^4)^-3#?
When you see a negative exponent, it means that the exponent's "home" is on the other level
Based off of that, let's rewrite this expression
Let's distribute that
Now we can move that
Now comes the fun part. When we are dividing variables, we subtract their exponents
