Evaluating Exponents of Negative Numbers 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 which would give the result 81.

Evaluating Exponents of Negative NumbersAn 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 which would give the result 81.
Evaluating Exponents of Negative NumbersIf 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
Evaluating Exponents of Negative NumbersThe negative number must be enclosed by parentheses to have the exponent apply to the negative term.
