Question

multiply.

\\-5u^4(-2u^3)\\

simplify your answer as much as possible.

Explanation:

Group coefficients and variables

$$ -5u^4(-2u^3) = (-5 \cdot -2)(u^4 \cdot u^3) $$

Multiply coefficients and apply exponent rule

$$ (-5 \cdot -2) = 10 $$

$$ u^4 \cdot u^3 = u^{4+3} = u^7 $$

Combine results

$$ 10u^7 $$

Answer:

Multiply.

$$ -5u^4(-2u^3) $$

Simplify your answer as much as possible.
