Question

$( \sqrt{ \frac{5}{7} }) ^{x - 1} = ( \frac{125}{343} ) ^{ - 1}$
solve the equation....​

Answer 1

Step-by-step explanation:

${(\sqrt{ \frac{5}{7} }}^{x - 1} = { (\frac{125}{343}) }^{ - 1}$

${ (\frac{5}{7}) }^{ \frac{x - 1}{2} } = { (\frac{5}{7}) }^{ - 3}$

$\frac{x - 1}{2} = - 3$

$x - 1 = - 6$

$x = - 5$

Therefore , it is your answer.
