**Reiny**, Wednesday, October 8, 2008 at 6:30pmthe decimal is always placed after the first signigicant digit, in your case 7.5, then count the number of decimal places it was moved. That becomes your exponent of 10

if you had to move to the right, the exponent is negative, if you moved to the left, the exponent is positive.

so .0075 = 7.5 x 10^{-4}

34567.21 = 3.456721 x 10^{4}
