a)
1,25 * (-3 i 1/4 ) = 1 i 1/4 * (-3 i 1/4 ) = 5/4 * (-13/4) = -65/16 = -4 i 1/16
b)
(-5 i 1/7 - 9/14 ):(-1 + 17/35 ) = (-36/7-9/14) : (-35/35+17/35) = (-72/14-9/14) : (-18/35) = -81/14*(-35/18) = 45/4 = 11,25
c)
(1 i 3/5 + 2,2 ): 6 i 1/3 = (1,6+2,2) : 19/3 = 3,8 : 19/3 = 38/10 * 3/19 = 6/10 = 0,6
d)
(-5 + 2 )² - (-2) * (-5)²= 3² - (-2)*25 = 9 - (-50) = 9+50 = 59
