Answer 1

Răspuns:

Explicație pas cu pas:

a = 5/9*9/25 - 2/25*25/10 = 1/5 - 1/5 = 0

________

0,8(3) = (83 - 8)/90 = 75/90 = 5/6

b = 3/2*(29/9 - 10/3)^2 + 5/6 = 3/2*(29/9 - 30/9)^2 + 5/6 = 3/2*1/81 + 5/6

= 1/54 + 5/6 = 1/54 + 45/54 = 46/54 = 23/27 = 0,(851)

_________

c = 0,2 - 0,2*(3/4 - 1/4) = 0,2 - 2/10*2/4 = 2/10 - 1/10 = 1/10 = 0,1

_________

a < c < b
