Answer 2

Answer:

x=9

Step-by-step explanation:

$(\frac{ - 5}{8} ) ^{x - 9} = 1$

$( \frac{ - 5}{8} ) ^{x} \times ( { \frac{ - 8}{5} })^{9} = 1$

$( \frac{ - 5}{8} ) ^{x} = ( \frac{ - 5}{8} )^{9}$

$since \: bases \: are \: equal \: equating \: the \: powers$

$therefore \: x = 9$

or simply,

x-9=0

therefore x=9

We know that only when power is equals to 0 the answer will be equal to 1
