A standard form should be in the form a.bcde ×10n The decimal point must be after the first non-zero digit. The n is the number of times the decimal point has to be moved to be right after the first non-zero digit. If it is moved to the left, the n is positive and if to the right, n is negative. Every whole number has .0 at the end but not written. 3560=3560.0 3560=3.560.0=3.56×103 Note: the power is positive because we have to move to the left.
