" 7-1Tho value of "(vec A+vec B)times(vec A-3)" is "

The value of (vec(A)+vec(B))xx(vec(A)-vec(B)) is

If vec a, vec b and vec c are non-coplanar vector and vec a times vec c is perpendicular to vec a times(vec b times vec c) ,then the value of [vec a times(vec b times vec c)]times vec c is equal to :

What is the value of (vec(A) + vec(B)) .(vec(A) xx vec(B)) ?

What is the value of (vec(A) + vec(B)) .(vec(A) xx vec(B)) ?

Two vectors vec(A) and vec(B) have magnitudes 2 and 2sqrt(2) respectively. It is found that vec(A).vec(B) = |vec(A) xx vec(B)| , then the value of |(vec(A)+vec(B))/(vec(A)-vec(B))| will be :

If vec a = 1/sqrt10 (3i+k) and vec b = 1/7 (2i+3j-6k) then the value of (2 vec a - vec b) . [(vec a xx vec b) xx vec a+ (vec a xx vec b) xx 2 vec b] is

If vec(a) and vec(b) are two vectors then the value of (vec(a) + vec(b)) xx (vec(a) - vec(b)) is

If vec(a) and vec(b) are two vectors then the value of (vec(a) + vec(b)) xx (vec(a) - vec(b)) is

If |vec a|=2,|vec b|=1 and vec a*vcb=1 then find the value of (3vec a-5vec b)*(2vec a+vec 7vec b)

If vec a and vec b are two vectors such that |quad vec a|=2 , |quad vec b|=1 and vec a. vec b=1 , then find the value of (3 vec a - 5 vec b).(2 vec a+7 vec b) .
