Quyidagi sonlardan qaysi birini kvadrat ildiz ostidan butun son qilib chiqarib bo'lmaydi?

  1. 1
  2. 25
  3. 256
  4. 678

📝 Detailed explanation

1, 25 va 256 sonlari to'la kvadratlar hisoblanadi (1², 5² va 16²). 678 soni esa hech qanday butun sonning kvadrati emas, shuning uchun uni ildizdan butun son holida chiqarib bo'lmaydi.
