## Evaluate Exponents

### Evaluate Exponents: Learn

An exponent is a number that tells how many times the base number is used as a factor.
For example, 3^{4} indicates that the base number 3 is used as a factor 4 times.
To determine the value of 3^{4}, multiply 3*3*3*3 = 81.

Exponents are written as a superscript number
(for example: 3^{4}) or preceded
by the caret (^) symbol (for example: 3^4).

Here are some special facts and properties about exponents:

- Any number raised to the zero power is 1 (7
^{0}=1) - Zero raised to any power (except zero) is zero (0
^{5}=0) - One raised to any power is one (1
^{5}=1)

Property #1 above is a little strange, and you will likely see a proof for
it when you are ready for formal algebra. When you see zero raised to the
zero power, Property #1 shows the result is actually 1. (0^{0}=1)
