+3454 So, we have to simplify [(x+5)-5]2
Based on the order of operations, we have to do everything in the () parentheses, then everything in the [] parentheses, then square that answer.
Think about this for a second. If you were to take a number, add five to it, then subtract five from it...what would you be left with? You'd be left with that original number!
Just to show you this, ill put in a couple different numbers for x.
--------------
[(9+5)-5]2
[(14)-5]2
92
--------------
[(7+5)-5]2
[(12)-5]2
72
--------------
So, we can simplify this expression to x2, because nomater what x is, if we add 5 then subtract 5 from it, we will still get x, then we square it to get x2.
