1.Oblicz :
a) 4/5 + (-1 i 1/5) : 2 i 2/5 + 3/8 * (-1 i 3/5 ) =
b) -12+4 * (-11)/4 - (-5)=
a) 4/5 + (-1 i 1/5) : 2 i 2/5 + 3/8 * (-1 i 3/5 ) = 4/5+(-6/5:12/5)+3/8*(-8/5)= 4/5 -6/5*5/12+3/8*(-5/8)= 4/5 - 30/60 - 15/64= 48/60-30/60-15/64=18/60-15/64= 1152/3840-900/3840= 252/3840=21/320
b) -12+4 * (-11)/4 - (-5)=-12+ 4/4*(-11/4)+5= -12-44/16+5=-528/16-44/16+80/16= 492/16=30.75
Proszę :)
