Question

simplify. express your answer using positive exponents.
$9vw^{8} \cdot 9vw$

Explanation:

Step1: Multiply the coefficients

$9 \times 9 = 81$

Step2: Combine like variable $v$

$v \times v = v^{1+1} = v^2$

Step3: Combine like variable $w$

$w^8 \times w = w^{8+1} = w^9$

Step4: Combine all terms

$81 \times v^2 \times w^9$

Answer:

$81v^2w^9$
