9x^6y^8.

Answer 2

9x^5y^6
6x^6y^8
9x^6y^8
none of the above

Answer 3

... 9x^6y^8.

Answer 4

\[\Large \begin{array}{l}
{\left( {3{x^3}{y^4}} \right)^2}\\
= \left( {3{x^3}{y^4}} \right)\left( {3{x^3}{y^4}} \right)\\
= 3{x^3} \cdot 3{x^3} \cdot {y^4} \cdot {y^4}\\
= 9{x^{3 + 3}}{y^{4 + 4}}\\
= 9{x^6}{y^8}
\end{array}\]
