Model cannot handle lg or triple root

[JavaZeroo]

Original img

model pred:

LaTeX Code: \sqrt[3]{(\\lg 50-1{)}^{3}}- \sqrt{(\lg 2-1{)}^{2}}=

What should I do to improve the model? 😥

Should I fine tune the model with larger dataset?

Really need your help! Thanks! 🙏🏻

I tried feeding more standard images into the model, but instead the model failed to recognise the formulae correctly.😥

model output:

\begin{array}{c c c c c}{{\varepsilon_{\bar{\vee}}\,4\sqrt{\left(\left|\,\vphantom{\cal G}\right.\ \!\lbrack\,\stackrel{\dagger}{\m}\rbrack\,\stackrel{\dagger}{\cal\sqrt}}\longrightarrow}}&{{\sqrt{\left(\left|\,\vphantom{\cal G}\right.\stackrel{\Sigma}{\Sigma}}\stackrel{\Sigma}{\longrightarrow}\stackrel{\Sigma}{\bf\Delta}}}&{{\longrightarrow}}&{{\sqrt{\left(\left|\,\left|\,\vphantom{\cal G}\right.\stackrel{\Sigma}{\cal\Delta}\right.\stackrel{\cal\Delta}\right.\longrightarrow}}}&{{\longrightarrow}}\end{array}
