If `veca=7hati+3hatj-6hatk`, `vecb=2hati+5hatj-hatk` and `vecc=-hati+2hatj+4hatk`. Find `(veca-vecb)xx(vecc-vecb)`.

If veca=7hati+3hatj-5hatk, vecb=2hati+5hatj-hatk and vecc-hati+2hatj+4hatk, then verify that vecaxx(b+c)=vecaxxvecb+vecaxxvecc

If veca=hati+hatj+hatk , vecb=2hati+hatj-hatk and vecc=4hati+3hatj+hatk then value of ((veca+vecb)xx(veca -(veca-vecb)xxvecb)))xxvecc is

If veca=2hati+3hatj+hatk, vecb=hati-2hatj+hatk and vecc=-3hati+hatj+2hatk , then [veca vecb vecc]=

If veca=2hati+2hatj-hatk, vecb=3hati-hatj-hatk and vecc=hati+2hatj-3hatk then verify that vecaxx(vecbxxvecc)=(veca.vecc)vecb-(veca.vecb)vecc .

If veca=2hati+5hatj-7hatk, vecb=-3hati+4hatj+hatk and vecc=hati-2hatj-3hatk , show that ((vecaxxvecb)xxvecc), vecaxx(vecbxxvecc) are not same .

If vecaa=hati+2hatj+3hatk, vecb=2hati-hatj+hatk and vecc=hati+hatj-2hatk, verify that vecaxx(vecbxxvecc)=(veca.vecc)vecb-(veca.vecb)vecc.

If veca=3hati+hatj-4hatk and vecb=6hati+5hatj-2hatk find |veca Xvecb|

Statement 1: vecA=2hati + 3hatj + 6hatk , vecB=hati + hatj - 2hatk and vecC=hati + 2hatj + hatk then |vecAxx (vecAxx(vecAxxvecB)).vecC|= 243 Statement 2: |vecAxx(vecAxx(vecAxxvecB)).vecC|=|vecA|^(2)|[vecA vecB vecC]|

If veca=2hati + hatj + hatk,vecb=hati + 2hatj + 2hatk ,vecc= hati + hatj + 2hatk and [vecavecbveci] hati+ [vecavecb vecj] hatj+ [veca vecb hatk] k is equal to
