Incorrect. Be sure you are excluding values for a that will make the numerator or the denominator of the divisor equal to 0. Then rewrite the expression as multiplication by the reciprocal and multiply normally: $\displaystyle\frac{{{12}{{a}}^{{5}}}}{{6}}\div\frac{{{6}{{a}}^{{3}}}}{{2}}=\frac{{{12}{{a}}^{{5}}}}{{6}}\cdot\frac{{2}}{{{6}{{a}}^{{3}}}}=\frac{{{24}{{a}}^{{5}}}}{{{36}{{a}}^{{3}}}}\usepackage{cmbright}\Huge\$ . Can you simplify this expression?
