U={1,2,3,4,5,6,7,8}
A={1,2,3,4,7,8}
B={1,2,4,5}

Determine (A'UB')n(AUB)'

• college Mathematics -

A' = {5,6)
B' = {3,6,7,8}
(A'UB') = {3,5,6,7,8}

(AUB)' = {6}

I don't understand the operator n
is it supposed to stand for "intersection" ?

if so, then

(A'UB') ∩ (AUB)' = {6}

if not, let me know what the n stands for

• college Mathematics -

yeah, u r very correct. n stands for intersection. ans=6

• college Mathematics -

yes Reiny it stands for intersection thank your help.

• college Mathematics -

f(x)= X2- 6x - 8
