The vectors a and b are not perpendicular and c and d are two vectors satisfying `b xx c = b xx d` and `a.d=0`. The vectors d is equal to

The vectors vec(a) and vec(b) are not perpendicular and vec(c ) and vec(d) are two vectors satisfying vec(b) xx vec(c )= vec(b) xx vec(d) and vec(a).vec(d)= 0 . Then the vector vec(d) is equal to

The vectors vec a and vec b are not perpendicular and vec c and vec d are two vectors satisfying : vec b""xxvec c""= vec b"" xxvec d"",vec a * vec d=0 . Then the vector vec d is equal to : (1) vec b-(( vec bdot vec c)/( vec adot vec d)) vec c (2) vec c+(( vec adot vec c)/( vec adot vec b)) vec b (3) vec b+(( vec bdot vec c)/( vec adot vec b)) vec c (4) vec c-(( vec adot vec c)/( vec adot vec b)) vec b

The vectors vec a and vec b are not perpendicular and vec c and vec d are two vectors satisfying : vec b""xxvec c""= vec b"" xxvec d"",vec a * vec d=0 . Then the vector vec d is equal to : (1) vec b-(( vec bdot vec c)/( vec adot vec d)) vec c (2) vec c+(( vec adot vec c)/( vec adot vec b)) vec b (3) vec b+(( vec bdot vec c)/( vec adot vec b)) vec c (4) vec c-(( vec adot vec c)/( vec adot vec b)) vec b

If a,b,c,d are four vectors then (A xx b) xx (C xx d) =
