If `AxxB={(1,2),(1,3),(1,6),(7,2),(7,3),(7,6)}` then find sets A and B.

If A+B={:[(7,6),(-3,2)]:}andA-B={:[(1,2),(3,6)]:} , then find A.

A and B are two sets and n(AxxB) =6 . If there elements of AxxB are (1,2) ,(2,3),(3,3), then find AxxB and BxxA .

A and B are two sets and n(AxxB) =6 . If there elements of AxxB are (1,2) ,(2,3),(3,3), then find AxxB and BxxA .

If A={:[(1,2),(3,4)]:}andB={:[(5,6),(7,8)]:} , then find 3A+7B.

If A=(1)/(7)[{:(6,-3,a),(b,-2,6),(2,c,3):}] is orthogonal, find a, b and c and hence A^(-1) .

Given that U={1,2,3,4,5,6,7,8} A={3,4,5}, B={5,6,7} then find A' cap B'.

Let A={1,2,3,4},B={5,6,7} and f={( 1,6),(2,7),(3,5),(4,6)} . The f is :

If A = {:[(4,2,7),(2,1,7)] and B = [(2,1,5),(3,4,6)] find 2A-B.
