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

If A xxB = {(p , q), (p , r), (m , q), (m , r)} , find A and B.

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

If P = {a , b , c} and A xxB = {(p , q), (p , r), (m , q), (m , r)} Q = {r} , form the sets P xxQ a n d Q xxP .Are these two products equal?

If P" "=" "{a ," "b ," "c} and A xxB" "=" "{(p ," "q)," "(p ," "r)," "(m ," "q)," "(m ," "r)} Q" "=" "{r} , form the sets P xxQ" "a n d" "Q xxP . Are these two products equal?

If A={:[(p,2),(-4,-5)]:},B={:[(q,r-s),(r,-5)]:}" and A=B. Find"{:[(p,q),(r,s)]:} , if the trace of A+B=-2.

If A={a,b,c), B={p,q,r} are subsets of R, p lt 0, r lt 0, q gt 0 and f={(a,p),(b,q),(c,r)} , then find sqrt(f) .

If P ={ a, b, c} and Q = {r} , find P xx Q .
