If |vec a xxvec b|=4,|vec a*vec b|=2 then |vec a|^(2)|vec b|^(2) is equals to-

If |vec a xx vec b| = 4 and |vec a . vec b| = 2, then |vec a|^(2) . |vec b|^(2) =

If | vec(a) xx vec(b) | =4 and | vec(a). vec(b) |=2 , then | vec( a) |^(2) | vec( b) | ^(2) is equal to

If (vec a xx vec b)^(2) + (vec a . Vec b)^(2) = 144 and |vec a| = 4 then |vec b| =
