parenthasees
exponentes
multiplcaiton or division
addition or subtraction

so first paretnehaseese
(7+4)
11

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

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

now we have
363-2
subtract
361

Well, first of all, i am separating the parts of the question to solve them individually and then put them back together..so
3(7+4)²
  7+4 is 11. so;
3(11)²
  this is the same as 3 x 11 x 11..and that is 363. anyway;
363   *

next;
14/7
  2 *
so, we have 363-2. that is 361. so your answer is 361. hope i . have a nice day

Welp life just is hard
