Please how can I write this equation in latex?

• What have you tried? Which part do you have trouble with? This is simply fraction and left right delimiter Oct 13 '15 at 16:42

Is it difficult?

\documentclass{article}
\usepackage{amsmath}

\begin{document}
$B_{v} = \frac{\mu_{0}I_{p}}{4\pi R}\biggl[\ln\biggl(\frac{8R}{a}\biggr) - \frac{3}{2} + \beta_{p} + \frac{l_{i}}{2}\biggr]$
\end{document}


• I guess it is difficult for the OP. Otherwise he wouldn't ask for help. Oct 13 '15 at 16:52
• @GonzaloMedina: I understood. :). That is why I answered. May be that phrase should be changed.. :)

\begin{equation*}
B_v = \dfrac{\mu_0 I_p}{4 \pi R} \left[ \ln \left( \dfrac{8 R}{a} \right) -dfrac{3}{2} + \beta_p + \dfrac{l_i}{2}\right]
\end{equation*}

• Please, don't use  in LaTeX. Oct 13 '15 at 16:47
• @egreg, I corrected it. But, why not? Oct 13 '15 at 16:50
