$$\frac{-b + \sqrt{b^2 - 4ac}}{2a}$$

$$\frac{F_le_a^{K}\times in^g}{V}$$

$\LaTeX$ 好评！

$\LaTeX$

~~NO UBB~~

eeeeee

\begin{equation} \frac{-b + \sqrt{b^2 - 4ac}}{2a} \end{equation}

如何在博客里提到某个人啊？

$$L^AT_EX$$

$$\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{L^AT_EX}}}}}}}}}}$$

这个公式渲染有毒 $$ \sqrt {\sqrt {\sqrt {\sqrt {\sqrt {\sqrt {\sqrt {\sqrt {\sqrt {\sqrt {\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt {\sqrt {\sqrt {\sqrt {\sqrt{\sqrt {\sqrt {\sqrt {\sqrt {\sqrt{\sqrt {\sqrt {\sqrt {\sqrt {\sqrt{1}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} = \LaTeX $$ $$\mu(n) =\left\{ \begin {array} {lr} 1&n=1 \\ (-1)^k&{\prod _{ i = 1 }^k q _ { i } = 1}\\ 0&(otherwise) \end {array} \right.$$

$\LaTeX$好啊

$\cfrac{-b+\sqrt{b^2-4*a*c}}{2a}$

$$1+1=2$$.
