Plz help me solve it the question is below
AlladinOne [14]

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}
