fully simplify.
$-9x^4y(-2y)$
answer attempt 1 out of 5

Explanation:

Step1: Multiply the coefficients

Multiply -9 and -2. So, \((-9)\times(-2) = 18\).

Step2: Multiply the variables with the same base

For the \(y\) terms, use the rule \(a^m\times a^n=a^{m + n}\). Here, \(y\times y=y^{1+1}=y^2\). The \(x^4\) term remains as it is since there's no other \(x\) term to multiply with.

Step3: Combine the results

Combine the coefficient and the variables. So, we get \(18x^4y^2\).

Answer:

\(18x^{4}y^{2}\)
