\(\left(8 \times 10^{5} \mathrm{~m}\right)^{3}\)

A customer borrows \(\$ 8500\) for 6 years at a simple interest rate of \(11.3 \%\). Find the simple interest.

The length of a rectangle is \(8 \mathrm{in}\). longer than the width. a. If \(W=\) width, write a polynomial expression in \(W\) that represents the length, and draw a diagram of the rectangle. Do not include the units. b. Write a polynomial expression in \(W\) that represents the perimeter. c. Write a polynomial expression in \(W\) that represents the area.

Problem: Simplify: \(\left(7 n^{4}\right)\left(9 n^{6}\right)\) $$ \text { Incorrect Answer: } \begin{aligned} &\left(7 n^{4}\right)\left(9 n^{6}\right) \\ &=63 n^{(4)(6)} \\ &=63 n^{24} \end{aligned} $$ 95\. Problem: Simplify: \(\frac{15 n^{12}}{3 n^{4}}\) $$ \text { Incorrect Answer: } \begin{aligned} & \frac{15 n^{12}}{3 n^{4}} \\ &=5 n^{12+4} \\ &=5 n^{3} \end{aligned} $$
