If you are writing in the input box you can enter

 

sqrt(5)     which will give you     $${\sqrt{{\mathtt{5}}}}$$             Note that this is the same as  5^(1/2)          $${{\mathtt{5}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right)}$$

 

OR

 

sqrt(5,3)   which will give you     $${\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{5}}}}$$          Note that this is the same as  5^(1/3)          $${{\mathtt{5}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)}$$
