Simplify and write with positive exponents only
%28x%5E2%29%5E-3%28x%5E-2%29%2F%28x%5E2%29%5E-4
First we can simplify the numerator and the denominator by using the rules for multiplying exponents.
%28x%5E-6%29%28x%5E-2%29%2F%28x%5E-8%29
Then we can add the exponents in the numerator...
%28x%5E-8%29%2F%28x%5E-8%29
Then we perform the indicated operation...
%28x%5E-8%29%2F%28x%5E-8%29=+1
The final result is 1
I hope this helps
Good Luck!
