Chapter 13.2, Problem 19AR

To determine

To simplify. Use only positive exponents ${\left(b^4\right)}^2$.

Answer to Problem 19AR

The required solution is ${\left(b^4\right)}^2=b^8$ .

Explanation of Solution

Given information: The number is ${\left(b^4\right)}^2$ .

Calculation: The required solution is obtained as,

When there is a power to a power like this, you just multiply the exponents together.

  $\begin{array}{l}{\left(b^4\right)}^2\\ =b^{4\times 2}\\ =b^8\end{array}$

Hence, the required solution is ${\left(b^4\right)}^2=b^8$ .
