Answer 1

⠀

$\huge\sf\red{\underline{\underline{Question \: :-}}}$

$\sf{}$

$\large\bf\binom{ \: - 2 \: }{ \: \: 3 }^{ - 2} \: \times \: \binom{ \: - 2 \: }{ \: \: 3 }^{7} \: \times \: \binom{ \: - 2 \: }{ \: \: 3 } ^{ - 4}$

$\sf{}$

$\huge\sf\purple{\underline{\underline{Solution \: :-}}}$

$\sf{}$

$\implies = \large \bf\binom{ \: - 2 \: }{ \: \: 3} ^{ - 2 \: + \: 7 \: + \: ( - 4)}$

$\implies = \large \bf\binom{ \: - 2 \: }{ \: \: 3} ^{ 5 \: - 4}$

$\implies = \large \bf\binom{ \: - 2 \: }{ \: \: 3} ^{ 1}$

$\implies = \large \bf\binom{ \: - 2 \: }{ \: \: 3}$

Answer 2

Answer:

$\huge{ \pink{ \underline{ \underline{Solution :-}}}}$

$\implies \: ( \frac{ - 2}{3} ) {}^{ - 2 + 7 + ( - 4)}$

$\implies \: ( \frac{ - 2}{3} ) {}^{5 - 4}$

$\implies \: ( \frac{ - 2}{3} ) {}^{1}$

$\implies \: ( \frac{ - 2}{3} )$
