`5^2-2(4-3)`

To evaluate, apply the order of operation known as PEMDAS.

So, do the operation inside the parenthesis first.

Since 4-3=1, then the expression becomes:

`=5^2-2*1`

Next, do the operation indicated by the given exponent.

`=25-2*1`

Notice that the remaining operations are subtraction and multiplication. Since multiplication comes before subtraction in PEMDAS, the next step is to multiply 2 and 1.

`=25-2`

And then, subtract.

`=23`

**Hence, `5^2-2(4-3)=23` .**

distribute the -2

`5^2-8+6 `

Following PEMDAS do the exponent next

25-8+6

17+6

=23
