Simplifying Expressions With Negative Exponents Learning Outcomes Use the properties of exponents to simplify products and quotients that contain negative exponents and variables All the exponent properties we developed earlier in this chapter with whole number exponents apply to integer exponents, too. Whether to include a negative sign as part of a base or not often leads to confusion. Watch this tutorial to see how you can evaluate an exponent by first writing it in expanded form. [latex]\left(5x\right)3=8,000[/latex] when [latex]x=4[/latex]. In the example below, notice how adding parentheses can change the outcome when you are simplifying terms with exponents. Again, I can work either of two ways: multiply first and then handle the negative exponents, or else handle the exponents and then multiply the resulting fractions. Students will find the cubes or squares of the given numbers as indicated. Why not publish the test class as well? The second expression includes parentheses, so hopefully you will remember that the negative sign also gets squared. When an exponent is negative, the negative sign is removed by reciprocating the base and raising it to the positive exponent.
