-6(3)squared+2 to the third power-8

I just put it straight on the web2 calc.

 

$${\mathtt{\,-\,}}{\mathtt{6}}{\mathtt{\,\times\,}}{{\mathtt{3}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{2}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)}{\mathtt{\,-\,}}{\mathtt{8}} = -{\mathtt{60.740\: \!078\: \!950\: \!105\: \!126\: \!8}}$$
