Step 1: First, we will convert the number 100.11 to scientific notation. After that, we will multiply the result by 10³.

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).

1.00.11

Step 3: We moved the decimal point 2 spaces to the right. Therefore, the exponent on base 10 will be positive 2.Now we know that the:

Mantissa = 1.0011

Exponent = 2

So, the solution is:

$$100.11 = \color{blue}{ 1.0011} \cdot 10^{ \color{red}{ 2 }}$$

Step 4: Now we need to multiply the above result by $10^{ 3 }$.

$$ 1.0011 \cdot 10^{ 2 } \cdot 10^{ 3 } = 1.0011 \cdot 10^{ 2+3 } = 1.0011 \cdot 10^{ 5 } $$
