Answer 1

$\huge\boxed{\underline{\bf { \red S \green O \pink L \blue U \orange T \purple I \red O \pink N \green{..}}}}$

$\longmapsto \sf\bigg( { \frac{ - 2}{3} \bigg) }^{4} \times \bigg( { \frac{7}{9}\bigg) }^{ - 4} \times \frac{2}{3}$

$\longmapsto \sf\bigg( { \frac{ - 2}{3} \bigg) }^{4} \times \bigg( { \frac{9}{7}\bigg) }^{4} \times \frac{2}{3}$

$\longmapsto \sf\bigg( { \frac{ - 2}{3} \times \frac{9}{7} \bigg) }^{4} \times \frac{2}{3}$

$\longmapsto \sf\bigg( { \frac{ - 2}{1} \times \frac{3}{7} \bigg) }^{4} \times \frac{2}{3}$

$\longmapsto \sf\bigg( { \frac{ - 6}{7} \bigg) }^{4} \times \frac{2}{3}$

$\longmapsto \sf \frac{1296}{2401} \times \frac{2}{3}$

$\longmapsto \sf \frac{432}{2401} \times 2$

$\longmapsto \sf \frac{864}{2401}$
