Question
If 
are non-coplanar vectors and λ is a real number then 
for -
are non-coplanar vectors and λ is a real number then for -Options
A.exactly two values of λ
B.exactly three values of λ
C.no value of λ
D.exactly one value of λ
Solution
L. H. S = 
=
[a b c]
R. H. S. =
⇒ λ4 [a b c] = - [a b c]
⇒ λ4 = - 1 which is not possible.
=
[a b c]R. H. S. =
⇒ λ4 [a b c] = - [a b c]
⇒ λ4 = - 1 which is not possible.
