# Math Help - Change size

1. ## 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

Rapha

3. thanks it is enough

4. \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

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

5. Thanks very much I use two way

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