Explicație pas cu pas:
a)
(-5/12 + 7/8 - 1/24)^0 * (6/5)^2
prima paranteza nu are sens sa o rezolvam, pentru ca orice numar la puterea 0 = 1
1*(6/5)^2 = 36/25
b)
7/3 *0 - 5*(1/2 : 1/5 - 17*3/34)
7/3*0 = 0
0 - 5*(1/2*5/1 - 3/2) = -5*(5/2 - 3/2) = -5*2/2 = -5*1 = -5
c)
1/4 : [5/4 - 2/3*(1.5^2 - 1.5)]
= 1/4 : [5/4 - 2/3*(2,25 - 1,5)]
= 1/4 : (5/4 - 2/3*0,75)
= 1/4 : (5/4 - 2/3*75/100)
= 1/4 : (5/4 - 2/3*3/4)
= 1/4 : (5/4 - 2/4)
= 1/4 : 3/4
= 1/4 * 4/3
= 1/3
