Find the product. Simplify your answer.

Question

(
–
7u2)(4u2)

Answer 1

To find the product of \((-7u^2)(4u^2)\), you can multiply the coefficients and the variables separately.

1. Multiply the coefficients: \(-7 \times 4 = -28\)

2. Multiply the variable parts: \(u^2 \times u^2 = u^{2+2} = u^4\)

Now, combine the two results:

\[ (-7u^2)(4u^2) = -28u^4 \]

Thus, the simplified answer is:

\[ \boxed{-28u^4} \]
