Question

select factors to multiply. -4 w^9 d (-5) d (\square) \cdot w^9d \cdot d enter the result.

Explanation:

Step1: Multiply the constant terms

$\boldsymbol{-4 \times (-5) = 20}$

Step2: Combine like variable terms for $d$

$\boldsymbol{d \times d = d^{1+1} = d^2}$

Step3: Combine all terms

$\boldsymbol{20 \times w^9 \times d^2}$

Answer:

$20w^9d^2$
