Odpowiedź:
A) 1/4 * 4/5= 4/20 = 1/5
B) 5/4 / 1/2= 5/4 * 2 = 10/4 = 2.5
C) (16/6 + 9/6) / 10/4 = 25/6 * 4/10= 100/60= 1+ 2/3
D) 5/4^2 * 4^3 - ((7 * 24) / 24*25 - (6*25) / 24* 25) / 5 = 20 - 18/5 = 100/5 - 18/5 = 82/5 = 16+ 2/5= 16.40
E) (2 * (49/56 - 8/56) + 3^1/2)^2 - 2^1/2 = (2 * 41/56 + 3^1/2)^2 - 2^1/2 = (82/56 + 3^1/2)^2 - 2^1/2 =
F) 64 + 25 - (13/6)^2 = 89 - (169/36)= 89 - 4 + 25/36 = 84+11/36
