  1. \(\left(\frac1{16}\right)^{-0.75}+\left(\frac1{8}\right)^{-4/3}=\left(\frac1{16}\right)^{-3/4}+\left(\frac1{8}\right)^{-4/3}=8+16=24\).
  2. \((0.04)^{-1.5}-(0.125)^{-2/3}=(1/25)^{-3/2}-(1/8)^{-2/3}=125-4=121\).
  3. \(8^{9/7}:8^{2/7}-3^{6/5}\cdot3^{4/5}=8^{7/7}-3^{10/5}=8-9=-1\).
  4. \((5^{-2/5})^{-5}+((0.2)^4)^{-4}=5^2+(5^{-4})^{-4}=25+5^{16}=152587890650\).
