a) 8:(-1i3/5) - (4i1/2 * 1i2/3 - 3i3/4)

a) 8:(-1i3/5) - (4i1/2 * 1i2/3 - 3i3/4) = 8: (-8/5) - (9/2 * 5/3 - 15/4) = 8 * (-5/8) -(15/2 - 15/4) = -5 - (30/4 - 15/4) = -5 - 15/4 = -5 - 3i3/4= -8 i 3/4 - to jest licznik
1/2 * 2i1/2 = 1/2* 5/2 =5/4 - to jest mianownik
-8 i 3/4 : 5/4 = - 35/4 * 4/5 = -35/5 = - 7
