Following the Order of Operation, the first step would be to solve what is in parenthesis so:
7*(8)^2-3^2
Now, exponents:
7*64-9
Now multiply what you can:
448-9
and finally, subtract for your answer:
439

Yay. I get to answer a question that is actually fun.


7(6 + 2) ^2 - 3^2 7(8) ^2 - 3^2 7(64) - 9 448 - 9 439

Thus, your answer is:
439
