* Remove trailing zeros now you have 789 Insert a decimal point between the first and second digits now you have 7.89 Count the digits to the left of the first digit in this case 10 Multiply the number in step 2 by 10 raised to the power the number in the third step So you get 7.89 X 1010 It can also be expressed as 7.89E10
