Question

A={1,2,3}. B={0,2,3,4}. C={0,1,5,6,7}

Va rog ajutatima​ dau coroana


(AUB)UC
(AnB)UC
(A-B)UC
(AnB)nC
AU(BnC)
A-C
B-C
C-A
C-B

Answer 1

Răspuns:

(AuB)UC=(0,1,2,3,4,5,6,7)

AnB)UC=(0,1,2,3,5,6,7)

(A-B)UC=(0,1,5,6,7)

(AnB)nC=0

AU(BnC)=(0,1,2,3)

A-C=(2,3)

B-C=(2,3,4)

C-A=(0,5,6,7)

C-B=(1,5,6,7)

Answer 2

Răspuns:

Explicație pas cu pas:

(AUB)UC = {0,1,2,3,4,5,6,7}

(AnB)UC = {2,3} U C = {0,1,2,3,5,6,7}

(A-B)UC = {1} U C = {0,1,5,6,7}

(AnB)nC = ∅

A - C = {2,3}

B - C = {2,3,4}

C - A = {0,5,6,7)

C - B = {1,5,6,7}
