If vecX = vecA xx(vecB xxvecC), then vec...

If `vecX = vecA xx(vecB xxvecC)`, then `vecX` can be expressed as :

A

linear combination of `vecA ` and `vecB`

B

linear combinations of `vecB` and `vecC`

C

linear combation of `vecA` and `vecB`

D

`vecB( vecA. vecC) - vecC(vecB . vecA)`

Text Solution

Verified by Experts

The correct Answer is:
B, D
`X = vecA xx (vecB xx vecC)`
` = vecB(vecA. vecC)-vecC(vecB. vecA)`
Hence, `vecX` is a linear combination of vectros `vecB` and `vecC`.
