{{ printedBook.courseTrack.name }} {{ printedBook.name }} To calculate a power means to evaluate its value. For example is $2^3=8$ since it's a product with three twos as factors. Remember that any number raised to the power of $1$ is the base itself, and any non-zero number raised to the power of $0$ is $1.$ $\begin{aligned} 2^3=8\\ 4^1=4\\ 74^0=1 \end{aligned}$
