Step 1: Since 80000 do not have a decimal point, we will add one at the end of the number 80000.
80000.
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).
8.0000.
Step 3: We moved the decimal point 4 spaces to the right. Therefore, the exponent on base 10 will be positive 4.Now we know that the:
Mantissa = 8.0000 (which can be written as 8 )
Exponent = 4
So, the solution is:
$$80000 = \color{blue}{ 8 } \cdot 10^{ \color{red}{ 4 }}$$
