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).

1.8023413964463582932.452099868856

Step 2: We moved the decimal point 19 spaces to the right. Therefore, the exponent on base 10 will be positive 19.Now we know that the:

Mantissa = 1.8023413964463582932452099868856

Exponent = 19

So, the solution is:

$$18023413964463582932.452099868856 = \color{blue}{ 1.8023413964463582932452099868856} \cdot 10^{ \color{red}{ 19 }}$$
