    Change size

    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

    \frac{\left(\frac{(2x^2)z^{-5}}{3z^4}\right)^{-5}}{\left(\frac{(3x^4)(z^9)}{2x^{-6}}\right)^{3}}

    One possibility is \displaystyle, e. g.

    \frac{\displaystyle \left(\frac{(2x^2)z^{-5}}{3z^4}\right)^{-5}}{\displaystyle \left(\frac{(3x^4)(z^9)}{2x^{-6}}\right)^{3}}

    That's the only method I know
    Sorry

    \displaystyle works fine in general. Another thing you can do is use \dfrac rather than \frac for nested fractions. Thus:

    Code:
    \frac{\left(\dfrac{(2x^2)z^{-5}}{3z^4}\right)^{-5}}
    {\left(\dfrac{(3x^4)(z^9)}{2x^{-6}}\right)^{3}}
    gives

    \frac{\left(\dfrac{(2x^2)z^{-5}}{3z^4}\right)^{-5}}{\left(\dfrac{(3x^4)(z^9)}{2x^{-6}}\right)^{3}}

    {\frac{\displaystyle\left(\dfrac{(2x^2)z^{-5}}{3z^4}\right)^{-5}}{\displaystyle\left(\dfrac{(3x^4)(z^9)}{2x^{-6}}\right)^{3}}}
