## Evaluate Integers with Exponents

### Evaluate Integer 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.

If a negative number is raised to an even power, the result will be positive.

(-2)^{4} = -2 * -2 * -2 * -2 = 16

If a negative number is raised to an odd power, the result will be negative.

(-2)^{5} = -2 * -2 * -2 * -2 * -2 = -32

*However!* You might remember from the order of operations that
exponents have a higher importance than subtraction. The negative number
*must* be enclosed by parentheses to have the exponent apply to
the negative. The examples below show the difference:

(-2)^{4} = -2 * -2 * -2 * -2 = 16

-2^{4} = -(2 * 2 * 2 * 2) = -16
