Incorrect. This expression simplifies to $\displaystyle\frac{{{{a}}^{{{4}{\left({6}\right)}}}{{b}}^{{{3}{\left({6}\right)}}}}}{{{{a}}^{{{8}{\left({3}\right)}}}{{b}}^{{-{2}{\left({3}\right)}}}{{c}}^{{{3}{\left({3}\right)}}}}}\usepackage{cmbright}\Huge\$ . Can you use the rules of exponents to simplify it from here? Remember: $\displaystyle{{\left({{x}}^{{n}}\right)}}^{{m}}={{x}}^{{{n}{m}}}\usepackage{cmbright}\Huge\$ , $\displaystyle{{x}}^{{n}}{{x}}^{{m}}={{x}}^{{{n}+{m}}}\usepackage{cmbright}\Huge\$ , and $\displaystyle\frac{{{x}}^{{n}}}{{{x}}^{{m}}}={{x}}^{{{n}-{m}}}\usepackage{cmbright}\Huge\$ .
