## 3³√24+³√375

$$3\sqrt{8*3}+\sqrt{5*5*5*3}\\\\ =3*2\sqrt{3}+5\sqrt{3}\\\\ =6\sqrt{3}+5\sqrt{3}\\\\ =11\sqrt{3}\\\\$$

check

$${\mathtt{3}}{\mathtt{\,\times\,}}{\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{24}}}}{\mathtt{\,\small\textbf+\,}}{\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{375}}}} = {\mathtt{15.864\: \!745\: \!273\: \!381\: \!492\: \!2}}$$

$${\mathtt{11}}{\mathtt{\,\times\,}}{\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{3}}}} = {\mathtt{15.864\: \!745\: \!273\: \!381\: \!492\: \!2}}$$

See what you can do with a bit of reading on surds. :) You'd be surprized about how fast you will pick it up. Might be something good on youtube as well. I think Kahn Acadamy would be the first stop.
