1. The problem is unclear as given, but it appears to involve simplifying or solving an expression involving variables $x$ and $y$ and possibly powers or coefficients. 2. Since the input is ambiguous, let's assume the problem is to simplify the expression $3x \times x^2 \times 3y$. 3. Recall the rule for multiplying powers with the same base: $a^m \times a^n = a^{m+n}$. 4. Multiply the coefficients: $3 \times 3 = 9$. 5. Multiply the powers of $x$: $x \times x^2 = x^{1+2} = x^3$. 6. The variable $y$ remains as is. 7. Therefore, the simplified expression is $$9x^3y$$. 8. This is the final simplified form of the expression assuming the problem was to multiply $3x$, $x^2$, and $3y$ together.
