Question

If L = {1, 2, 3, 5, 6), M = {5, 6, 7} and N = {5, 7} then verify L - (MUN) = (L - M) n (L-N)​

Answer 1

Answer:

(MUN)={5,6,7}

(L-M)={1,2,3}

(L-N )={1,2,3,}

L-(MUN)={1,2,3}

L-(MUN)=(L-M)n(L-N)

Answer 2

$l = (1 \: 2 \: 3 \: 5 \: 6) \\ m = (5 \: 6 \: 7) \\ n = (5 \: 7) \\ \\to \: verify \\ l - (m \: n \: n) = (l - m) \: n \: (l - n) \\ \\ see \: the \: atachment \: please$

hey mate

there should be a slight change in question

there should be

L-(M n N) in the question...!!!
