Example 2
Simplify the expression [math]x^{–3} • y^0 • z^{–4} • x^5[/math]. Write the expression using only positive exponents. |
|
[list=1] [*]Use the exponent rule [math]a^m • a^n = a^{m + n}[/math] to simplify the expression. [*]Use the exponent rule [math]a^0 = 1[/math] to further simplify the expression. [*]Use the exponent rule [math]a^{-m} = \frac{1}{a^m}[/math] to write the negative exponent as a positive exponent.
