Step 1: Move the decimal point from its current position (the black dot) to a position immediately to the right of the first nonzero digit (the red dot).
4.732.66
Step 2: We moved the decimal point 3 spaces to the right. Therefore, the exponent on base 10 will be positive 3.Now we know that the:
Mantissa = 4.73266
Exponent = 3
So, the solution is:
$$4732.66 = \color{blue}{ 4.73266} \cdot 10^{ \color{red}{ 3 }}$$
