how simplify the question ​

Answer 1

Answer:

X = -2

Step-by-step explanation:

(4/5)^-3 x (4/5)^-9 = (5/4)^-6X

(4/5)^-3 x (4/5)^-9 = (4/5)^-(-6X)

(4/5)^-3 x (4/5)^-9 = (4/5)^6X

-3+(-9) = 6X

-12 = 6X

X = -2

Answer 2

Answer:

$x = - 2$

Step-by-step explanation:

$\red\dashrightarrow\underline{\underline{\sf \blue{( \frac{4}{5}) ^{ - 3} \times{( \frac{4}{5}) }^{ - 9} = {( \frac{5}{4} })^{ - 6x} }} }$

By a^m×a^n=a^mn

$\red\dashrightarrow\underline{\underline{\sf \blue{ ( \frac{4}{5}) ^{ - 12} = ( \frac{5}{4}) ^{ - 6x} }} }$
