use scientific notation to divide the following two numbers. Express the answer using scientific notation; retain at least three decimal places (8.4*10^6)/ (5.97*10^2)

First comment. In scientific notation, one should pay attention to significant digits, the 8.4 is two sig digits, which makes the answer only to two digits, not three.
8.4/5.97 *10^{62} you can do the math.
