Question

10) Determinar o conjunto X tal que:
I- {a, b, c, d } U X = { a, b, c, d, e }
II- {c, d } U X = { a, c, d, e }
III- { b, c, d } n X = {C}
a) a, b, c, e, }
b) {a, c, e)
c) {b, c, e}
d) {c, d, e}

Answer 1

Resposta:

I- {a, b, c, d} U X ={a, b, c, d, e}

= {a, b, c, d ,e } ,,

II-{c ,d} U X = {a , c , d , e}

={a,c,d , e}

III- {b, c, d} n X ={c}

={c}

III n a)

= {b, c}

III n b)

= {c}

III n c)

= {b ,c}

III n d)

={c ,d}
