₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋ =
(-2)²

b) ⅘ - (1,2 * ⁵/₁₂ - 0,8) : (-½)³=

c) (0,5)²- ⁵/₃₆
[ --------------- + 4 : 3,25] * √1 ²⁵/₁₄₄ - 1 ⁵/₁₂ =
¹/₉

Answer 1

a) (⅓)³ + √25 - 8 * 2⁻¹
₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋ =
(-2)²

1/27+5-8*1/2 /4=1/27+5-4=1/27+1=1i1/27
b) ⅘ - (1,2 * ⁵/₁₂ - 0,8) : (-½)³=4/5-1⅕*5/12-⅘):-1/8=4/5-(7/5*5/12)-⅘=4/5-7/12:(-1/8)=13/60*(-8/1)=-26/15

c) (0,5)²- ⁵/₃₆
[ --------------- + 4 : 3,25] * √1 ²⁵/₁₄₄ - 1 ⁵/₁₂ =1+4:3,25*1*√25/144-1⁵/ ₁₂=5*4/13*5/12-17/12=50/72-17/12=50/72-102/72=52/72=26/36=13/18
