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).

2.05303186613.42

Step 2: We moved the decimal point 11 spaces to the right. Therefore, the exponent on base 10 will be positive 11.Now we know that the:

Mantissa = 2.0530318661342

Exponent = 11

So, the solution is:
