Ответ:

  1. \(1.6\cdot(-11)=-17.6\).
  2. \((-0.7):(-17)=0.7:17=\frac{7}{170}\).
  3. \(0.6-1.738=-1.138\).
  4. \(0.6-1.738=-1.138\).
  5. \(13-1\frac{3}{8}=13-\frac{11}{8}=\frac{93}{8}=11\frac{5}{8}\).
  6. \(-3\frac{1}{8}-6.875=-3.125-6.875=-10\).
  7. \(-2\frac{3}{7}-\left(-4\frac{3}{7}\right)=2\).
  8. \((3^3)^2\cdot3^5:3^7:9=3^6\cdot3^5:3^7:3^2=3^2=9\).
  9. \((4^4)^2:2^{18}=4^8:2^{18}=2^{16}:2^{18}=\frac14\).
  10. \((5^4)^2\cdot125:25^5=5^8\cdot5^3:5^{10}=5\).
