is it possible to take the fourth root of a number on this calculator?

$$\sqrt[4]{625}=625^{1/4}$$

so you can enter    625^(1/4)

$${{\mathtt{625}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{4}}}}\right)} = {\mathtt{5}}$$

Yep...for instance  the 4th root of 6

Type in "6" 

Hit the   ^x√y   key  

Then, type in "4"

Hit  the  =   key

And that's it....
