If `A xx B={(p, q),(p, r),(m, q),(m, r)}`, fịnd `A` and `B`

Let A = {a, b, c}, B = {p, q, r} and f: A rarr B be given by f = {(a, q), (b, r), (c, p)}. will f^(-1) exist ? justify your answer.

If a !=p, b !=q, c!=r and |(p,b,c),(a,q,c),(a,b,r)| = 0 then the value of (p)/(p-a)+(q)/(q-b)+(r)/(r-c) is equal to a)-1 b)1 c)-2 d)2

|(1,1,1),(p,q,r),(p,q,r+1)| is equal to

Let A = [(a,b,c),(p,q,r),(x,y,z)anddet.(A)=2. Then the det. (B). Where B=[(4x,2a,-p),(4y,2b,-q),(4z,2c,-r)] , equals

If S(p, q, r) = (~p) vv [-(q ^^ r)] is a compound statement, then S(~p, ~q, ~r) is a) ~S(p, q, r) b) S(p, q, r) c) p vv (q ^^ r) d) p vv (q vv r)

If X = [(0,1),(0,0)] and (pI + qX)^(m) = AI + BX, AA p,q, in R, where A and B are scalars and I is two rowed unit matrix, then A and B are a) p^(m-1), mp^(m)q b) p^(m), mp^(m-1) q c) p^(m), mp^(m-2) q^(-1) d)None of these
