Some students evaluated teh problem and got 8 while others got 338.

It should be 328. The precedence of operation is as follows: exponentiation, division, multiplication and addition. Some got 8 because they first multiplied 4 with 9. However, since division and multiplication are of the same precedence, division is evaluated first.
