You move the variable and its exponent &lt;b&gt;&lt;i&gt;but not&lt;/i&gt;&lt;/b&gt; the coefficient if there is one to the numerator and drop the minus sign on the exponent.


*[tex \LARGE \frac{1}{ax^{-n}}\ =\ \frac{x^n}{a}]


But:


*[tex \LARGE \frac{1}{a\left(bx\right)^{-n}}\ =\ \frac{(bx)^n}{a}] 


John
*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
