i duzo punltow ;^^

Answer 1

a)2i1/5*10+1i3/4=11/5*10+1i3/4=110/5+1i3/4=22+1i3/4=23i3/4

2/3*1i4/5+2i1/2=2/3*9/5+5/2=18/15+5/2=36/30+45/30=81/30=2i21/30=2i7/10

b)3i3/4+2i2/3*2i1/4=3i3/4+8/3*9/4=3i3/4+72/12=3i3/4+6=9i3/4

[(3/2)^+7/6]*3=[9/4+7/6]*3=[27/12+14/12]*3=41/12*3=123/12=10i1/4

c)12/5*5/3-11/6=60/15-11/6=4-1i5/6=2i1/6

39/8-4/3*9/8=39/8-36/24=117/24-36/24=81/24=3i9/24=3i3/8

 

^ oznacza do kwadratu

Answer 2

a) 1¹/₅ · 10 + 1³/₄= ¹¹/₅ * 10=⁸⁸/₄+⁷/₄=⁹⁵/₄=23⁵/₄

²/₃·1⁴/₅+2²/₃·2¹/₄=²/₃·⁹/₅+⁸/₃·⁵/₄=⁶/₅+¹⁰/₃=¹⁸/₁₅+⁵⁰/₁₅=⁶⁸/₁₅=4⁸/₁₅

 

b)3³/₄+2²/₃·2¹/₄=¹⁵/₄+⁸/₃·⁹/₄=¹⁵/₄+⁶/₁=¹⁵/₄+²⁴/₄=³⁹/₄=9³/₄

[(1¹/₂)2+1¹/₆]·3=³/₂·²/₁+⁷/₆=¹⁸/₆+⁷/₆=²⁵/₆=4¹/₆

 

c)2⅖·1⅔-1⅚=¹²/₅·⁵/₃-¹¹/₆=⁴/₁-¹¹/₆=²⁴/₆-¹¹/₆=¹³/₆=2⅙

4⅞-1⅓·1⅛=³⁹/₈-⁴/₃·⁹/₈=³⁹/₈-³/₂=³⁹/₈-¹²/₈=²⁷/₈=3⅜
