If `vec(A)xxvec(B)=vec(C )`, then which of the following statements is wrong?

If vec a xxvec b = vec a xxvec c, vec a! = 0, then

If vec a xxvec b = vec a xxvec c, vec a! = 0, then

If vec a xxvec b = vec c, vec b xxvec c = vec a, then

If vec(a),vec(b),vec(c) are three non-coplanar vectors represented by concurrent edges of a parallelepiped of volume 4 cubic units, find the value of (vec(a)+vec(b))*(vec(b)xxvec(c))+(vec(b)+vec(c))*(vec(c)xxvec(a))+(vec(c)+vec(a))*(vec(a)xxvec(b))

Statement-I : The angle between vectors vec(A)xxvec(B) and vec(B)xxvec(A) is pi radian. Statement-II : vec(B)xxvec(A)=-vec(A)xx vec(B)

Statement-I : The angle between vectors vec(A)xxvec(B) and vec(B)xxvec(A) is pi radian. Statement-II : vec(B)xxvec(A)=-vec(A)xx vec(B)

If vec a xxvec b=vec c xxvec d and vec a xxvec c=vec b xxvec d then show that vec a-vec d is parallel to vec b-vec c where a!=d and b!=c

If vec a xxvec b = vec c xxvec d and vec a xxvec c = vec b xxvec d then show that vec a-vec d is parallel to vec b-vec c

If vec a xxvec b=vec c xxvec d and vec a xxvec c=vec b xxvec d then show that vec a-vec d ,is paralelto vec b-vec c provided vec a!=hat d and vec b!=vec c
