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).
4.6260134.02
Step 2: We moved the decimal point 7 spaces to the right. Therefore, the exponent on base 10 will be positive 7.Now we know that the:
Mantissa = 4.626013402
Exponent = 7
So, the solution is:
$$46260134.02 = \color{blue}{ 4.626013402} \cdot 10^{ \color{red}{ 7 }}$$
