$\alpha  = \left( {\begin{array}{*{20}{c}}
  m \ 
  2 
\end{array}} ight)\,$   $\alpha  = \frac{{m(m - 1

Vedclass · Accepted Answer

$3 \cdot \left( {\,_{\,\,\,\,\,4}^{m + 1}\,} \right)$

Vedclass · Answer

$\alpha  = \left( {\begin{array}{*{20}{c}}
  m \ 
  2 
\end{array}} ight)\,$   $\alpha  = \frac{{m(m - 1)}}{2}\,$

હવે $\,\left( {\begin{array}{*{20}{c}}
  \alpha  \ 
  2 
\end{array}} ight)\,\,\, = \left( {\frac{{m(m - 1)}}{{\begin{array}{*{20}{c}}
  2 \ 
  2 
\end{array}}}} ight)\,$

$ = \frac{1}{2}.\frac{{m(m - 1)}}{2}\,.\,\left[ {\frac{{m(m - 1)}}{2} - 1} ight] = \frac{1}{8}m(m - 1)({m^2} - m - 2)$

$ = \frac{1}{8}m(m - 1)(m + 1)(m - 2)$

$ = 3\left[ {\frac{1}{{24}}(m + 1)(m)(m - 1)(m - 2)} ight]$

$ = 3.\frac{{(m + 1)(m)(m - 1)(m - 2)}}{{4\,!}} = 3\,.\,\left( {\begin{array}{*{20}{c}}
  {m + 1} \ 
  4 
\end{array}} ight)$

જો $\alpha = \left( {\begin{array}{{20}{c}}
m \\
2
\end{array}} \right)\,\,$ હોય ,તો $\left( {\begin{array}{{20}{c}}
\alpha \\
2
\end{array}} \right) = ......$
