what is the cube root of 729

$${\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{729}}}}$$

 

$${\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}}}$$

 

$${\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}$$

 

$${\mathtt{9}}$$

 

$${\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{729}}}} = {\mathtt{9}}$$
