Evaluate the expression 3(7 + 4)^2 − 14 ÷ 7.

3 (7 + 4)² - 14 ÷ 7
3 (11)² - 14 ÷ 7
3 (121) - 14 ÷ 7
363 - 14 ÷ 7
363 - 2
361

I hope this helps.
361 is the answer.
to answer this question you would have to do PEMDAS
parentheses
exponents
multiplication or division
addition or subtraction

so first parenthesis
(7+4)
11

now we have
3(11)^2-14/7
exponents
11^2=121

now we have
3(121)-14/7
multiply
3 times 121=363
division
14/7=2

now we have
363-2
subtract
361
