NEITHER! Look at 4+8 which you know is 12 4 is 2^2 and 8 is 2^3 2^2+2^3=12 but no power of 2 is equal to 12? So the answer is NEITHER. When you multiply numbers, you add the exponents and when you raise and exponent to a power, you multiply exponents. In the example i gave, you could factor out the smallest power and you have 2^2(1+2)=2^2x3=4x3=12 That is how you do this type of problem. Either raise the numbers to their powers and add them, or factor and add.
