Answer:
361
Step-by-step explanation:
To solve this you need to use the Order of Operations or PEMDAS.
The Order of Operations is Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.(PEMDAS)
So first you need to solve what's in the parentheses which is 7 + 4, this equals 11.
Then rewrite the problem as 3*11^2 - 14/7
Next you need to solve the exponents which is 11 squared. So 11 squared equals 121.
3*121 - 14/7
Now you need to multiply 3 by 121 since multiplication comes next in the order of operations. So 3*121 = 363
363 - 14/7, Next you need to divide 14 by 7 which is 2.
363 - 2, 363 subtracted by 2 is 361
