9191

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+411+4 which is 1515. You would then do multiplication with 5(15)5(15) as there are no exponents and obtain 7575. After this, you can simply add 16 to get 9191!

You could also take 55 and multiply it by 1111 and 44 separately to obtain 7575 without actually adding 1111 and 44. That would look like 5555 (from 511) and 2020 (from 54), adding to 7575 which is the same as before!
