Answer 2

`19`

Explanation:

To simplify this we need to follow the order of operations.

We begin with:
`2(4^2-3)-7`

First, we need to simplify the exponent

`2(16-3)-7`

Next, we need to do everything within the parenthesis

`2(13)-7`

Now we can multiply

`26-7`

And lastly, we can subtract

`19`
