Ответ:

  1. \(2^3\cdot2^4=2^{3+4}=2^7=128\).
  2. \(3^{13}:3^9=3^{13-9}=3^4=81\).
  3. \(7^5\cdot7^{12}:7^{14}=7^{5+12-14}=7^3=343\).
  4. \(37^8:37^7\cdot37=37^{8-7+1}=37^2=1369\).
  5. \(\left(-1\frac79\right)^{10+12-20}=\left(-1\frac79\right)^2=\left(-\frac{16}{9}\right)^2=\frac{256}{81}\).
  6. \(\frac{5^{12}\cdot5^4}{5^{13}}=5^{12+4-13}=5^3=125\).
  7. \(\frac{(0,3)^{9+18}}{(0,3)^{23+4}}=(0,3)^{27-27}=(0,3)^0=1\).
  8. \(2^3\cdot128=2^3\cdot2^7=2^{10}=1024\).
  9. \(81:3^3\cdot3^4=3^4:3^3\cdot3^4=3^{4-3+4}=3^5=243\).
  10. \(\frac{625\cdot5^3}{5^5}=\frac{5^4\cdot5^3}{5^5}=5^{4+3-5}=5^2=25\).
