What is the value of 2^3 + 3^2?

The correct answer is: 17

To find the value of $2^3 + 3^2$, we need to evaluate each component separately. First, $2^3$ means $2$ multiplied by itself $3$ times: \[ 2^3 = 2 \times 2 \times 2 = 8 \] Next, $3^2$ means $3$ multiplied by itself $2$ times: \[ 3^2 = 3 \times 3 = 9 \] Now we add the results of $2^3$ and $3^2$: \[ 8 + 9 = 17 \] Thus, the value of $2^3 + 3^2$ is $17$. This corresponds to the second choice. Understanding these basic exponentials and performing the addition correctly leads us to the right result.
