\"\"

\
\

The principal square root of \"\" is \"\", and the principal cube root of \"\" is \"\".

\

Hence, \"\" is an integer.

\

For example \"\" power of an integer, Since \"\".

\

The principal square root of \"\" is \"\", and the principal cube root of \"\" is \"\".

\

Here \"\" and \"\" are integers.

\
\

Therefore \"\" and \"\"  are the examples numbers for which the both principal square root

\

and principal cube root are  integers.
