Question

if x/y =(-1/3)^-3÷(2/3)^-4 find(x/y)^-1​

Answer 1

Answer:plz mark my answer as brainlist

$\frac{x}{y} = \frac{ (\frac{ - 1}{3}) ^{ - 3} }{ (\frac{2}{3})^{ - 4} } \\ \\ \frac{x}{y} = \frac{ (\frac{3}{ - 1} ) ^{3} }{ (\frac{3}{2} ) ^{4} } \\ \\ \frac{x}{y} = \frac{ \frac{27 }{ - 1} }{ \frac{81}{16} } \\ \\ \frac{x}{y } = \frac{27}{ - 1} \times \frac{16}{81} \\ \\ \frac{x}{y} = \frac{ - 16}{3} \\ \\ (\frac{x}{y} )^{ - 1} = \frac{ - 16}{3} \\ \\ \frac{y}{x} = \frac{3}{ - 16}$
