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, 34 indicates that the base number 3 is used as a factor 4 times. To determine the value of 34, 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
-24 = -(2 * 2 * 2 * 2) = -16
