oblicz wyrażenie
W zależności od postaci licznika podaję dwa rozwiązania:
(1)
[2,5 + (2/3 - 1,8 * 5/6)]/(-1/3)^3 =
= [25/10 +(2/3 - 9/6)]/(-1/27) =
=[ 5/2 +(4/6 - 9/6)]/(-1/27) =
= (15/6 -5/6)/(-1/27) =
= 10/6 :(-1/27) =
= 5/3 *(-27) =
= -45
=======
LUB
(2)
2,5 +(2/3 -1,8 *5/6)/(-1/3)^2 =
= 2,5 +(4/6 - 9/6)/(-1/27) =
= 2,5 +(-5/6)/(-1/27) =
= 2,5 +(-5/6)*(-27) =
= 2,5 + 22,5 =
= 25
