Pilne na teraz!! pomóżcie! Oblicz:
a) 5/6 - (o,6: 3/8-1,6)=
b) 1 1/4-0,25*4+6 1/2):3
c)(6-2*2 1/2)*(1,5)-1(<--do potęgi)
d)(√2/5)2(do potęgi)- (1,2*5/12-0,8*1/23

b ) ( 1/4 - 25/100 *4/1 + 6 i 1/2 ) :3 = (1/4 - 5/4 +6i 1/2 ) :3 = (-4/4 +6i 1/2 ) ;3 = (-1+6 i 1/2 ) :3 = 5 i 1/2 :3 = 11/6
d) ( pierwiastek 2/5 ) razy 2 tam jest i do potęgi ?
