Question

simplify. express your answer using positive exponents.
(10u⁶)(7u)

Explanation:

Step1: Multiply the coefficients

Multiply 10 and 7.
$10\times7 = 70$

Step2: Multiply the variables with exponents

Use the rule $a^m \times a^n = a^{m + n}$. Here, $u^6\times u = u^{6+1}=u^7$.

Step3: Combine the results

Combine the coefficient and the variable part.
$70\times u^7 = 70u^7$

Answer:

$70u^7$
