Step 1: Since 233435655433100890188923456639999234208891 do not have a decimal point, we will add one at the end of the number 233435655433100890188923456639999234208891.

233435655433100890188923456639999234208891.

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).

2.33435655433100890188923456639999234208891.

Step 3: We moved the decimal point 41 spaces to the right. Therefore, the exponent on base 10 will be positive 41.Now we know that the:

Mantissa = 2.33435655433100890188923456639999234208891

Exponent = 41

So, the solution is:

$$233435655433100890188923456639999234208891 = \color{blue}{ 2.33435655433100890188923456639999234208891} \cdot 10^{ \color{red}{ 41 }}$$
