Question

Oblicz wartości wyrażeń. a) (-0.25)² : (-⅛) : (-2)² - (-1000)⁰ = b) [ (-0.5)³ + 2¼ ] : [ (-0.25) + (-2)² ] = c) -(-5)² · 1/5₃ - (2.3 - 2½)² = d) -4² - 0.4³ : (-0.64) - (½)⁰ = e) -2² - (13 - 7²) - (-0.1)³ · 10³ = Proszę z rozwiązaniami!! ;)

Answer 1

a) =0,0625/(-1/3)/4-1=625/10000*(-3)*1/4-1=-1875/40000-1=1 1875/40000=1 3/64

b) =[0,25+2 1/4]/[0,0625+4]=2,5/4,0625=25/10*10000/4625=1000/185=5 75/185= 5 15/37

c) = -25*1/5-(-0,2)^=-5-0,04=5,04

d) = -16-0,064/(-0,64)-1=-16-0,1-1=-17,1

e) = -4-(13-49)-0,01*100=-4+36-1=31
