You can put this solution on YOUR website!
%28%28a%5E3%29%5E2b%5E2%29%2F%28ab%29%5E2
First term in numerator: %28a%5E3%29%5E2=a%5E6
Second term in numerator: b%5E2=b%5E2
Denominator:%28ab%29%5E2=a%5E2b%5E2
Put it all back together:
%28a%5E6b%5E2%29%2F%28a%5E2b%5E2%29=
b%5E2 cancel leaving a%5E6%2Fa%5E2=a%5E4
NOTE: %28a%5E3%29%5E2=a%5E3%2Aa%5E3=a%5E6
