Question

a) 8 ½ - 6,322 + 2 ⅜

b) 6 ⅓ - (4,12 + 2,18)

c) 5,68 - 1 ³/₁₄ + 2,12 - 5 ⁹/₁₄

d) 5,8 - 5 ⁸/₉ + 3,4 - 3 ³/₂₇

Answer 1

a) 8 ½  - 6,322 + 2 ⅜ = 8,5 - 6,322 + 2.375 = 2.1170 + 2.375 = 4.553

 

b) 6 ⅓ - (4,12 + 2,18) = 19/3 - 6.3 = 19/3 - 6 i 3/10 = 19/3 - 63/10 = 190/30 - 189/30 = 1/30

 

c) 5,68 - 1 ³/₁₄ + 2,12 - 5 ⁹/₁₄ = 5,68 - 17/14 + 2.12 - 79/14 = 5 i 68/100 - 17/14 + 2 i 12/10 - 79/14 = 568/100 - 17/14 + 32/10 - 79/14 = -96/14 + 568/100 + 32/10 = -96/14 + 568/100 + 320/100 =

-96/14 + 888/100 = - 4800/700 + 6216/700 = 1416/700 ≈ 2.023

 

d) 5,8 - 5 ⁸/₉ + 3,4 - 3 ³/₂₇ = 5 i 8/10 - 54/9 + 3 i 4/10 - 84/27 = 58/10 - 54/9 + 34/10 - 84/27 = 92/10 - 162/27 - 84/27 = 92/10 - 246/27 = 2484/270 - 2460/270 = 24/270 = 12/135 = 4/45

 

Mam nadzieję, że jest dobrze. Obliczenia wyszły na serio dziwne.
