Best ResponseYou've already chosen the best response.0The 2.4 in the top will be cancelled with the one in the bottom. You will be left with 4.8 times some powers of 10's. When you multiply numbers that have the same base you add powers, and when you divide them you subtract powers. So the answer will be \(4.8 \times 10^{8+53}=4.8 \times 10^{6}\).
