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

Use the exponent rule $x^a \cdot x^b = x^{a + b}$. For $x^3 \cdot x$, we have $x^{3 + 1}=x^4$

Step3: Multiply the y terms

Use the exponent rule $y^a \cdot y^b = y^{a + b}$. For $y \cdot y$, we have $y^{1+1}=y^2$

Step4: Combine the results

Combine the coefficient, x term, and y term. So we get $-108x^4y^2$

Answer:

$-108x^4y^2$
