Using Exponents in Algebra
You might like to read the page on Exponents first.
Whole Number Exponents
The exponent "n" in an says
how many times to use a in a multiplication:
Example: 53 = 5 × 5 × 5 = 125
- The "3" says to use 5 three times in a multiplication
- In words: 53 could be called "5 to the third power", "5 to the power 3" or simply "5 cubed"
Negative Exponents
A negative exponent a-n is equal to 1/an (1 divided by the positive exponent)
Example:
5-3 = 1/53 = 1/125 = 0.008
Also ...
by changing the signs of the exponents we get:
A positive exponent an is equal to 1/a-n (1 divided by the negative exponent)
So, we can move an expression between the top and bottom (numerator and denominator) of a fraction when we also change the sign of the exponent.
Example: 5-3 = 1/53 = 1/125 = 0.008
Positive and Negative Together
Here is an example with positive and negative exponents:
Example: 432-59-132
We can put the values with negative exponents at the bottom (remembering to make the exponents positive):
