1. matritsalar ustida amallar

2.1. a) = 3^.5–(-4)^.2 = 15+8 = 23

b) =^. – (-1)^.a = a+a = 2a

2.2. Uchinchi tartibli determinantlarni uchrurchaklar usuli, Sarryus usuli hamda biror ixtiyoriy satr yoki ustun elementlari bo’yicha yoyib hisoblang:

a) =1^. (-3)^.(-5) + 1^.1^.4 + 2^.(-1)^.1 – 1^.(-3)^.4 – 1^.2^.(-5) – 1^.(-1)^.1 = = 15 + 4 – 2 + 12 + 10 + 1 = 40

b) = 15 – 2 + 4 + 12 + 1 + 10 = 40

c) = 1 - 1 + 1 = 16 + 14 + 10 = 40
