Answer 2

Answer:

$-\frac{125}{27}$

Step-by-step explanation:

$(-\frac{3}{5} )^{-3}$ = $-(\frac{3}{5})^{-3}$ = $-(\frac{(3)^{-3} }{(5)^{-3} } )$ = $-(\frac{(\frac{1}{3})^{3} }{(\frac{1}{5} )^{3} } )$                    [∵ $x^{-2} = (\frac{1}{x} )^{2} = \frac{1}{x^{2} }$]

                                           = $-(\frac{5^{3} }{3^{3} } )$ = $-\frac{125}{27}$
