can I change the size of the text in latex if I can how?
because sometimes when you write a large data it is become small like this
$\displaystyle \frac{\left(\frac{(2x^2)z^{-5}}{3z^4}\right)^{-5}}{\left(\frac{(3x^4)(z^9)}{2x^{-6}}\right)^{3}}$

\displaystyle works fine in general. Another thing you can do is use \dfrac rather than \frac for nested fractions. Thus:
givesCode:\frac{\left(\dfrac{(2x^2)z^{-5}}{3z^4}\right)^{-5}} {\left(\dfrac{(3x^4)(z^9)}{2x^{-6}}\right)^{3}}
$\displaystyle \frac{\left(\dfrac{(2x^2)z^{-5}}{3z^4}\right)^{-5}}{\left(\dfrac{(3x^4)(z^9)}{2x^{-6}}\right)^{3}}$
