91

Explanation:

Keep in mind what the order of operations is! Remember:
Parentheses - Exponents - Multiplication - Division - Add - Subtract, starting with Parentheses.

So, in this problem, you would start with 11+4 which is 15. You would then do multiplication with 5(15) as there are no exponents and obtain 75. After this, you can simply add 16 to get 91!

You could also take 5 and multiply it by 11 and 4 separately to obtain 75 without actually adding 11 and 4. That would look like 55 (from 511) and 20 (from 54), adding to 75 which is the same as before!
