fully simplify.
$-15x^{3}y^{5}(-11y^{4})$

Explanation:

Step1: Multiply the coefficients

Multiply -15 and -11.
\( (-15) \times (-11) = 165 \)

Step2: Multiply the variables with the same base (y)

Use the rule \( a^m \times a^n = a^{m + n} \) for \( y^5 \) and \( y^4 \).
\( y^5 \times y^4 = y^{5 + 4} = y^9 \)

Step3: Combine the results

The \( x^3 \) term remains as it is since there is no other x term to multiply with. So we combine the coefficient, \( x^3 \), and the combined y term.
\( 165x^3y^9 \)

Answer:

\( 165x^3y^9 \)
