Răspuns:
X = {1,2 ; 6/5 ; 1/2 ; 7/4 ; 4/3}
Explicație pas cu pas:
M = { 1,44 ; 36/25 ; 4/16 ; 3intregi si 1/16 ; 1,(7) }
X = ? x = √y ; y ∈ M
√1,44 = 1,2
√(36/25) = 6/5
√4/16 = 2/4 = 1/2
3intregi si 1/16 = (3·16+1)/16 = 49/16
√(49/16) = 7/4
1,(7) = (17-1)/9 = 16/9
√(16/9) = 4/3
X = {1,2 ; 6/5 ; 1/2 ; 7/4 ; 4/3}
