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.
