\"\"

\

The binomial series is \"\".

\

\"\" can be written as \"\".

\

Binomial series is \"\"

\

Therefore substiute \"\" and \"\".

\

\"\"

\

\"\"

\

\"\"

\

If we move the starting from \"\" to \"\" then

\

\"\".

\

\"\"

\

Now find the radius of convergence, the series is not much different than the standard binomial series form so,

\

probably this will converge when \"\" or \"\".

\

\

The ratio test states that :

\
(1).If \"\"  then the series converges absolutely.
\
\
(2).If  \"\" then the series does not converge.
\
\
(3).If \"\" or the limit fails to exist then the test is inclusive because there exist both
\
convergent and divergent series that satisfy this case.
\
 
\
\"\"
\
 
\
\"\"
\
 
\
Therefore the result is same, converges if \"\" , therefore \"\".
\
\"\"
\
 
\
\"\" and \"\".
