80 or 5(4)^2 you first do parenthesis and then the square root so you would have 5(4)^2 Then, you would do the square root and it would come out to 5(16) You can simply multiply from there, 80.
This can be found by using PEMDAS. First you'd solve the parenthesis. 1 + 3 = 4. Next you'd solve the exponents. 4 ^ 2 (4 * 4) = 16. Finally you'd multiply 16 by 5 to get an answer of 80.
