Ответ:

  1. \(3^2+4^2=9+16=25\).
  2. \(3^3+2^3=27+8=35\).
  3. \(26^2-(12^2\cdot3+175)=676-(144\cdot3+175)=676-(432+175)=676-607=69\).
  4. \(6^3-2\cdot4^3-1^3=216-2\cdot64-1=216-128-1=87\).
  5. \(15^2:(13^2-124)=225:(169-124)=225:45=5\).
  6. \(8^3:(4^2-2^3)=512:(16-8)=512:8=64\).

Ответ: 1) 25; 2) 35; 3) 69; 4) 87; 5) 5; 6) 64.
