The decimal point is at the END of the number, so it needs to be moved to create a number that is between 1 and 10. You determine your exponent/base 10 power on the number of spaces the decimal was moved 2 2 0 0 0 = ______________ 3 6 0 0 0 0 = ___________ 5 2 5 = __________ When expressing very small numbers (less than 1) in scientific notation, the process is essentially the same, however the decimal point is moving in the opposite direction, so the exponent in the base 10 power will be NEGATIVE. 0 . 0 0 0 0 0 8 8 = _______________ 0 . 0 0 9 5 6 = ________________ 0 . 0 0 0 0 1 4 = ______________ How do you put numbers that are in scientific notation back into standard form? If the exponent is positive, that indicates a big, so move the decimal point to the RIGHT. If the exponent is negative, that indicates a small number, so move the decimal to the LEFT a) 2 . 6 5 x 10-3 = ______________________ b) 8 . 3 5 x 10-5 = _____________________ c) 1 x 100 = ___________________
