$\frac{9^x-4^x}{9^x+6^x}$

$\frac{(3^x)^2-(2^x)^2}{ (3\times 3)^x + (2\times 3)^x }$

$\frac{(3^x-2^x)(3^x+2^x)}{3^x(3^x+2^x) }$

$\frac{3^x-2^x}{3^x}$

$This can be the final answer, though you can write it as:$

$1 - (\frac{2}{3})^x$

Mate kurt, how the fuck do you type it online. I was gonna reply to this but I couldn't type it out. Kurt's answer is right by the way. Muppy, you need to see your teachers.

how do u use LaTex

Either download the latex script, or go to the maths section, and above quick replies there is the latex code button, click on it, type up your equation and it will give you the LaTeX script for it.

The best internet guide is at About LaTeX

in this forum, you must enclose the code in

$code [/ tex] for [/ tex] there is ment to be no space between the forward slash and 'tex' (The reason why i wrote it like that is because it would become the code ;D$
