Step 1: Since 79814000 do not have a decimal point, we will add one at the end of the number 79814000.

79814000.

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).

7.9814000.

Step 3: We moved the decimal point 7 spaces to the right. Therefore, the exponent on base 10 will be positive 7.Now we know that the:

Mantissa = 7.9814000 (which can be written as 7.9814 )

Exponent = 7

So, the solution is:
