If `A= {x in N:xle4}`, `B= {y in N:3leyle5}` ,writedown `Axx A`,` AxxB`, `BxxA` and `BxxB`

If x in N ,solve 4x + 5 < 2x + 17

If A = {1, 3, 5}, B = {2, 4, 6}, represent Axx A and AxxB graphically.

If A= {x : x in N, 2 < x < 7} and B= {x : x in N, 5 < x < 8} , find A capB .

If A = {4, 5, 7}, B= {2, 4} and C= {2, 3, 7}, find Axx(BcapC)

A= {1, 3, 2), B = {4} and C= {5}, Verify that Axx(B-C)=(AxxB)-(AxxC)

If A=(x:x in N,x is divisible by 2},B=(x:x²-3x +2=0},find A∩B.

A= {1, 3, 2), B = {4} and C= {5}, Verify that Axx(BcupC)=(AxxB)cup(AxxC)

A= {1, 3, 2), B = {4} and C= {5}, Verify that Axx(BcapC)=(AxxB)cap(AxxC)

If n(A')=15 , n(B)=5 , n(A nn B)=3 and n( uu ) = 30 then determine n(A) , n(A uu B) and n(A-B) where A and B are subset of a universal set U.
