Step 1: Since 98 do not have a decimal point, we will add one at the end of the number 98.
98.
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).
9.8.
Step 3: We moved the decimal point 1 spaces to the right. Therefore, the exponent on base 10 will be positive 1.Now we know that the:
Mantissa = 9.8
Exponent = 1
So, the solution is:
$$98 = \color{blue}{ 9.8} \cdot 10^{ \color{red}{ 1 }}$$
