✍︎ Scientificnotationis a method of writing large and small numbers, which is usually written as 10 raised to the proper exponent x times a number n, such that n is a number between 1 and 10. It can be expressed as .
The proper exponent is the number of digits past the original decimal point the decimal point has moved to the left or right.
xis positive if the decimal point has moved to the left, and
x is negative if the decimal point has moved to the right.
Determine n by placing the decimal point one digit past the first nonzero digit to the right. Thus, n= 6.5 . Note that the decimal point moved 8 places to the left, so x is positive.
