Answer 2

HERE IS UR ANSWER DEAR,

$( { \frac{3 }{7} )}^{4} \times { \frac{3}{7} }^{ - 5} = { \frac{3}{7} }^{2} m + 1$

${( \frac{3}{7} )}^{ - 1} = {( \frac{3}{7} )}^{2} m + 1$

$\frac{7}{3} - 1 = { \frac{3}{7} }^{2} m$

$\frac{7 - 3}{3} = \frac{9}{49} m$

$m = \frac{4}{3} \times \frac{49}{9}$

$m = \frac{196}{27}$
