3(7 + 4)2 − 14 ÷ 7
First do the parenthesis
7 + 4 = 11
so the question looks like: 3(11)2 - 14/7
Then multiply 3, 11, and 2 together
3 x 11 x 2 = 66
66 - 14/7
14/7 equals to 2
66 - 2
Then just simplify
66 - 2 = 64
64 is your answer
hope this helps

I am assuming that (7 + 4)2 means (7 + 4)^2. The 2 is an exponent.
You must follow the correct order of operations.
PEMDAS
P - parentheses first
E - then Exponents
MD - then Multiplications and Divisions in the order they appear from left to right
AS - then Additions and Subtractions in the order they appear from left to right
3(7 + 4)^2 − 14 ÷ 7
Parentheses first:
3(11)^2 - 14 ÷ 7
Now the exponent:
3(121) - 14
÷ 7
Now multiplications and division from left to right:
363 - 2
Finally additions and subtractions from left to right:
361
