If `A={x:x=6n,ninWandnlt6},B={x:x=2n,ninNNand2ltnle9}andC={x:x=3n,ninNNand4lenlt10}`, then show that `A-(BcapC)=(A-B)cup(A-C)`

If A={y:y=(a+1)/2,ainWandale5},B={y:y=(2n-1)/2,ninWandnlt5}andC={-1,-1/2,1(3)/(2),2} , then show that A-(BcupC)=(A-B)cap(A-C) .

If P = {x:x inNNand1ltxlt11},Q={x:x=2n,ninNNandnlt6} and R = {4, 6, 8, 9, 10, 12}, then verify P-(QcapR)=(P-Q)cup(P-R) .

If A={x:x=2^(n),n inWandnlt4},B={x:x=2n,n inNNandle4} and C = {0, 1, 2, 5, 6}, then verify the associative property of intersection of sets.

If A={a : a in N, 2 le a lt 6}, B={b : b in N, b lt 10}, C={x: x^(2)-7x+10=0} , then verify that A-(B cup C)=(A-B) cap (A-C)

If A = {1, 3, 5, 7, 9}, B = {x : x is a composite number and xlt12 } and C = {x:x inNand6ltxlt10} then verify Acup(BcapC)=(AcupB)cap(AcupC) .

If A={x:x inZZ,-2ltxle4},B={x:x inW,xle5} , C = {-4, -1, 0, 2, 3, 4}, then verify Acup(BcapC)=(AcupB)cap(AcupC) .

Let A ={X in W |x lt 2 } , B ={x in N | 1 lt x le 4 }m and C = {3,5} . verify that A xx (B nnC)=( A xx B) nn (A xx C)

If U={x:x inNN,xle10} , A = {2, 3, 4, 8, 10} and B = {1, 2, 5, 8, 10}, then verify that n(AcupB)=n(A)+n(B)-n(AcapB)

If U={x:x inNNandxlt10} , A = {1, 2, 3, 5, 8} and B = {2, 5, 6, 7, 9}, then n[(AcupB)'] is
