Multiplying a real number by a positive power of ten moves the decimal point that number (the exponent) of places to the right. Step One: Rewrite the Value with Negative Exponent as a Fraction Since we are performing division (the inverse of multiplication), we will rewrite the value as a fraction with a numerator of one. Move the decimal points n places, if it is a positive move towards the right if the exponent is negative move towards the left. Download FREE Study Materials Decimal Worksheets The number of moves of the decimal point gives you the exponent, which is always positive for a big number.

After attaining a perfect 800 math score and a 690 English score on the SAT, David was awarded the Dickinson Scholarship from the University of Miami, where he graduated with a Bachelors degree in Business Administration. One way you could think of a negative exponent is that it's telling you to move the location of the factor - when the move is made, the exponent becomes positive. When you multiply by moving the decimal point to the right, you also need to add a zero to the end of it. The exponent, or power of 10, increased by 1 because we moved the decimal place one space to the left. > Writing numbers in scientific notation vs decimal notation < /a > exponents powers 5 as an example, 9.31 10 5 = 931000 large numbers that decimal.
