Answer 1

Answer:

$\sf{\implies{\dfrac{3^\frac{-6}{7}\times4^\frac{-3}{7}\times9^\frac{3}{7}\times2^\frac{7}{6}}{2^{2}+2^{0}+2^{-2}}}}$

$\sf{=\dfrac{3^\frac{-6}{7}\times3^\frac{6}{7}\times2^\frac{6}{7}\times2^\frac{-6}{7}}{2^{2}+1+\frac{1}{2^{2}}}}$

$\sf{=\dfrac{2}{\frac{21}{4}}}$

$\sf{=\dfrac{8}{21}}$
