Question

How can we change a number to scientific notation?

Answer 1

To change from standard form to scientific notation:
(1) Place the decimal point such that there is one non-zero digit to the left of the decimal point.
(2) Count the number of decimal places the decimal has "moved" from the original number. This will be the exponent of the 10.
(3) If the original number was less than 1, the exponent is negative; if the original number was greater than 1, the exponent is positive.
