5.Ejercicios:

a.A={(3X-2)/x ∈ N;10 < x < 12}
b.B={(5x-2)/x ∈ N, 7 < x < 9}
c.T={(3X-2)/x ∈ N, 2 < x < 5}
d.U={(5x-2)²/x ∈ N, 3 < x < 6}
e.D={(X-1)/x ∈ N, 9 > x > 5}

Answer 1

a.A={(3X-2)/x ∈ N;10 < x < 12}  = ( 31 )
b.B={(5x-2)/x ∈ N, 7 < x < 9} = ( 38 ) 
c.T={(3X-2)/x ∈ N, 2 < x < 5} = ( 7 , 10 ) 
d.U={(5x-2)²/x ∈ N, 3 < x < 6} = ( 324 , 529 ) 
e.D={(X-1)/x ∈ N, 9 > x > 5} = (5 , 6 , 7 )
