Ответ:

  1. \(2^2-3\sqrt5\cdot8\sqrt5=4-24\cdot5=4-120=-116\).
  2. \(3^{1+2\sqrt[3]{2}}:9^{\sqrt[3]{2}}=3^{1+2\sqrt[3]{2}}:(3^2)^{\sqrt[3]{2}}=3^{1+2\sqrt[3]{2}-2\sqrt[3]{2}}=3\).
  3. \((5^{1+\sqrt2})^{1-\sqrt2}=5^{(1+\sqrt2)(1-\sqrt2)}=5^{1-2}=5^{-1}=\frac15\).
  4. \((5^{1-\sqrt5})^{1+\sqrt5}-(\sqrt5)^0=5^{(1-\sqrt5)(1+\sqrt5)}-1=5^{1-5}-1=5^{-4}-1=\frac1{625}-1=-\frac{624}{625}\).

Ответ: 1) \(-116\); 2) 3; 3) \(\frac15\); 4) \(-\frac{624}{625}\).
