If A = {x^2 | x in N, x le 5} and B = {x^3 | x in N, x < 6}, then find A n B.

If M = {x | x is a multiple of 5} : N = {x | x is a multiple of 7}, then M n N =

If A = {x| x is a multiple of 2, x in N} B = {x| x is a multiple of 5, x in N }, C= {x| x is multiple of 10, x in N}, then (A nn B) nn C=

If A={ x/x in N , x is a factor of 6}, B={ x/x in N , x is a factor of 8} then find A-B

Which of the following sets are equal? : P = {x | x in W, x is a multiple of 2} : Q = {x | x is an even number, x > 1} : R = {x | 2x = n, n in N}

Find the intersection of each of the following set: C={x|x in N, 5 lt x le 10} , D = {y|y in W, 5 le y lt 10}

If A = {x//x is a multiple of 2,x in N }, B={x| x is a multiple of 5,x in N}, C= {x|x is multiple of 10, x in N}, then A nn(B nn C)=
