Answer:

Hello mate!

= (-2)^{-5} ÷   \frac{2^{-3}*3^{7}  }{3^{-6}*2^{-5}  }

= (-2)^{-5} ÷  \frac{2^{-3}*2^{5}  }{3^{-6}*3^{-7}  }

= (-2)^{-5} ÷ \frac{(2)^{-3+5}  }{(3)^{-6-7}  }

= \frac{1}{(-2)^{5} }  ÷ \frac{(2)^{2}  }{(3)^{-13}  }

= \frac{-2^{5} }{1}  × \frac{(2)^{2}  }{(3)^{-13}  }  

= \frac{(-2)^{7} }{(3)^{-13} }     =\frac{-1*(2)^{7} }{(3)^{-13} }

= \frac{-1}{2^{7}* 3^{-13}  }
