Ok, use the order of operations. (PEMDAS)
Parentheses first. 7-2 is 5.
Now you have 5 squared X 2
According to the order of operations, you do exponents next.
5 squared is 25.
So now you have 25 X 2
25 X 2 is 50. So your final answer is 50!

(7-2)^2 *2
=5^2 *2 or = (7^2 - (2*7*2) + 2^2) *2
=25 *2 or = (49-28+4)*2
=50 or = 25*2
=50
Ans: 50

always do what is in the parenthesis first...

7^2 - 2^2 = 49 - 4 = 45...WRONG
