We need to solve this by PEMDAS. P=parenthesis, E=exponents, M=multiplication, D=Division, A=Additions, S=Subtraction. First we solve this problem by solving the inside of the parenthesis, 5*3, which is 15. The next step is E, exponents, we use 15 to the second power to get 225, and then we add 3 to the 225, and the total of this problem is 228.
