# How to you use LaTeX?

I've been trying hard to make the latex work but it always dosent.. how do you show powers in LaTeX?

$$\sum_{i=1}^{11} 2^i = 2^1 + 2^2 + \ldots + 2^{11}$$

$$\frac{2}{3}$$

Remember to wrap math in $$...$$ or $...$ to ensure proper formatting.
2 \times 3 $$2 \times 3$$
2^{34} $$2^{34}$$
a_{i-1} $$a_{i-1}$$
\frac{2}{3} $$\frac{2}{3}$$
\sqrt{2} $$\sqrt{2}$$
\sum_{i=1}^3 $$\sum_{i=1}^3$$
\sin \theta $$\sin \theta$$
\boxed{123} $$\boxed{123}$$

Sort by:

you can use " \displaystyle{} " to solve this problem. Put your code in "{ }" of "\displaystyle{}". this is the example. I put "\displaystyle{\sum_{i=1}^3}" inside \­( ...\­)and get something like this. $$\displaystyle{\sum_{i=1}^3}$$

Jo,

Check out the formatting guide. It explains how to use Latex, I have also inserted two examples into the body of your discussion post. Use your edit feature to see what I have changed. Good luck!
