Question 181039
{{{((a^3)^2b^2)/(ab)^2}}}
First term in numerator: {{{(a^3)^2=a^6}}}
Second term in numerator: {{{b^2=b^2}}}
Denominator:{{{(ab)^2=a^2b^2}}}
Put it all back together:
{{{(a^6b^2)/(a^2b^2)}}}=
{{{b^2}}} cancel leaving {{{a^6/a^2}}}={{{a^4}}}

NOTE: {{{(a^3)^2=a^3*a^3=a^6}}}

Hope this helps---ptaylor
