Algebra I: Calculating and working with negative exponents
This is a free lesson from our course in Algebra I
Here you'll learn how to work with negative exponents. One of the important rule for a negative exponent is:
                     (a)-m = 1/am
For example, 3-3 is same as 1 over 33. The lesson also explains how to use the rule when the value of a is in fraction. For example, (2/5)-3.
A negative exponent means how many times to divide by the number. For example: 8-1 = 1 8 = 1/8 = 0.125 Or many divides: Example: 5-3 = ((1 5) 5) 5 = 0.008 But that can be done an easier way: 5-3 could also be calculated like: 1 (5 5 5) = 1/53 = 1/125 = 0.008.
That last example showed an easier way to handle negative exponents: A-n = 1 / an
