Question

simplify. express your answer using positive exponents. (8u)(4u)

Explanation:

Step1: Multiply coefficients

Multiply 8 and 4: $8\times4 = 32$.

Step2: Multiply variables

Multiply $u$ and $u$ using the rule $a^m\times a^n=a^{m + n}$, so $u\times u=u^{1 + 1}=u^2$.

Step3: Combine results

Combine the results of step 1 and step 2: $32u^2$.

Answer:

$32u^2$
