GEMDAS or PEMDAS can be used. First grouping, in this case the square root of 25 which equals 5. Next, exponents. 4 squared equals 16.
16-5*2
multiply or divide before addition or subtraction (unless parenthesis is used)
16-10 equals 6.
6 is your answer. Hope this helps!

16-10=6 so the answer is 6
