4 500 000 soni berilgan bo'lsin. Agar u a × 10⁶, b × 10⁷, c × 10⁹ va d × 10⁴ ko'rinishlarida yozilsa, d ÷ c − a ÷ b ning qiymatini toping.

  1. 9999
  2. 99990
  3. 99999
  4. 99900

📝 Detailed explanation

Har bir harfning qiymatini mos ravishda aniqlaymiz: a = 4,5; b = 0,45; c = 0,0045; d = 450. Ifodaga qo'yamiz: 450 ÷ 0,0045 − 4,5 ÷ 0,45 = 100 000 − 10 = 99 990.
