Ответ:

  1. 6) \(512:8^2=512:64=8\).
  2. 7) \(16:4^3=16:64=\frac14\).
  3. 8) \(3^5:162=243:162=\frac32\).
  4. 9) \(10^4:2^4=10000:16=625\).
  5. 10) \(8^2:4^3=64:64=1\).
  6. 13) \(24\cdot(\frac1{20})^2-19\cdot\frac1{20}=\frac{24}{400}-\frac{19}{20}=\frac3{50}-\frac{95}{100}=\frac6{100}-\frac{95}{100}=-\frac{89}{100}\).
  7. 14) \(36\cdot(\frac12)^3+20\cdot(\frac12)^2=\frac{36}{8}+\frac{20}{4}=\frac92+5=\frac{19}{2}\).
