So... this problem tests whether we can actually use the PEMDAS mantra.

First we deal with the parentheses and get 7 minus 4 is 3...

Then we take care of the exponents... 2 to the 3rd is 2 times 2 times 2,

which is 4 times 2, which is 8... which is great.

And 5 cubed is 5 times 5 times 5, which is 25 times 5, which is 125.

So now we have a mere multiplication problem -- 8 plus 125 times 3.

Since 125 times 3 is the "M" part of PEMDAS, we have to do it before doing any addition...

...and we get 125 times 3, which equals 375.

Now add 8 to get 383.

And the answer is... C.
