Evaluate. `5^2-2(4-3)` 5to the second power-2(4-3). Show as much work as possible.Im a 55 year old mom trying to help her adhd child learn this. I never was good at math
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:
Next, do the operation indicated by the given exponent.
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.
And then, subtract.
Hence, `5^2-2(4-3)=23` .
