Question

plzzz..solve this.....it's urgent...​

Answer 1

Answer:

(3/4) ^6

Step-by-step explanation:

(4/5) ^0=1

x/y=(3/4)^-3

(x/y)^-2= (3/4) ^(-3×-2) =(3/4) ^6

Answer 2

$\boxed { \frac{x}{y} = ( \frac{3}{4} ) {}^{ - 3} \div ( \frac{4}{5} ) {}^{0} } \\ \frac{x}{y} = \frac{4}{3} \div \frac{1}{1 } \\ \frac{x}{y} = \frac{3}{4} \\ \boxed{ \red{ To \: Find \: \: (\frac{x}{y} {})^{ - 2} } = ( \frac{3}{4} ) {}^{ - 2} = (\frac{4}{3} ){}^{2} = \frac{16}{9} }$
