Step 1: Since 1650000000000 do not have a decimal point, we will add one at the end of the number 1650000000000.
1650000000000.
Step 2: 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).
1.650000000000.
Step 3: We moved the decimal point 12 spaces to the right. Therefore, the exponent on base 10 will be positive 12.Now we know that the:
Mantissa = 1.650000000000 (which can be written as 1.65 )
Exponent = 12
So, the solution is:
$$1650000000000 = \color{blue}{ 1.65} \cdot 10^{ \color{red}{ 12 }}$$
