If `A = {1, 1}`, find `A xxA xxA`.

If A ={-1,1} , find A xx A xxA

If A ={2,1} , find A xx A xxA

If A ={2,1} , find A xx A xxA

If A= {-1, 2, 3} and B= {1, 3} , the determine B xxA

If A = {a,b} and B = {1,2,3} then (A xxB) nn (B xxA)=

If A = {a,b} and B = {1,2,3} then (A xxB) nn (B xxA)=

If A = {1,2,3} and f,g are relations corresponding to the subset of A xxA indicated against them,which of f,g, is a function? Why? F(1,3),(2,3),(3,2) , g = (1,2),(1,3),(3,1)

Let S={1,2,3,4,5} and A=S xx.A relation R on A is defined as follows '(a,b)R(c,d) iff ad=cb. Then R is

DeltaLMN~DeltaPQR , 9xxA(DeltaPQR)=16xxA(DeltaLMN) . If QR=20 , then find MN .

DeltaLMN~DeltaPQR,9xxA(DeltaPQR)=16xxA(DeltaLMN) . If QR = 20 , then find MN.
