Vectors aa n db make an angle theta=(2pi)/3dot If | vec a|=1,| vec b|=2, then [( vec a+3 vec b)xx(3 vec a- vec b)]^2 is equal to 225 b. 250 c. 275 d. 300

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

If two vectors vec a and vec b are such that |vec a|=2,|vec b|=1 and vec a*vec b=1, find (3vec a-5vec b)*(2vec a+7vec b)

If two vectors vec a and vec b are such that | vec a|=2,| vec b|=1 and vec adot vec b=1 , find (3 vec a-5 vec b)dot(2 vec a+7 vec b)dot

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

if vec a*vec b=0&vec c makes an angle of (pi)/(3) with both vec a&vec b then [vec avec bvec c]^(2) can be

If vec(a) and vec( b) are inclined at an angle of 120^(@) and |vec(a)| =1, |vec(b)|=2 , then t ((vec(a) + 3 vec(b)) xx (3 vec(a) - vec(b)))^(2) is equal to
