Plz help me solve it the question is below

Answer 1

Answer:

$\frac{1024}{2025}$

Step-by-step explanation:

$\frac{3}{4}^{-4} = \frac{1}{\frac{3}{4}^{4} }$

(3/4)^4 = 81/256

1 ÷  81/256 = 256/81

So;

$\frac{256}{81} * \frac{4}{9} = \frac{1024}{729}$

$\frac{1024}{729} / n = \frac{1}{9/25}$

$\frac{1024}{729n} = \frac{25}{9} \\\\n = \frac{1024 *9 }{25 * 729} = \frac{1024}{2025}$
