question
fully simplify.
$9x^{3}y(-12xy)$
answer attempt 1 out of 2

Explanation:

Step1: Multiply the coefficients

Multiply 9 and -12: \( 9 \times (-12) = -108 \)

Step2: Multiply the \( x \)-terms

Using the rule \( a^m \times a^n = a^{m + n} \), for \( x^3 \times x \): \( x^{3 + 1} = x^4 \)

Step3: Multiply the \( y \)-terms

Using the same rule, for \( y \times y \): \( y^{1 + 1} = y^2 \)

Step4: Combine all parts

Multiply the results from Step1, Step2, and Step3: \( -108x^4y^2 \)

Answer:

\( -108x^4y^2 \)
