10. Ifodalarning qiymatini amallarning to‘g‘ri tartibida hisoblang. a) 2100 − (1856 + 114) : 300 · 150; b) 49000 : (3412 − 2712) : 10 + 3419

a)

Avval qavs ichidagi amalni bajaramiz: \(1856+114=1970\).

So‘ng bo‘lish va ko‘paytirishni chapdan o‘ngga hisoblaymiz: \(1970:300\cdot150=\frac{1970}{300}\cdot150=985\).

Endi ayiramiz: \(2100-985=1115\).

b)

Avval qavs ichidagi ayirishni bajaramiz: \(3412-2712=700\).

Bo‘lish amallarini chapdan o‘ngga bajarib, so‘ng qo‘shamiz: \(49000:700:10+3419=70:10+3419=7+3419=3426\).

Javob: a) 1115; b) 3426.
