If `veca=2hati+2hatj-3hatk, vecb=hati-2hatj+2hatk, vec c=4hati+3hatj+3hatk` then find the value of `|veca+2vecb+2vec c|`

If veca=2hati+3hatj-hatk, vecb= -hati+2hatj-4hatk, vec c =hati+hatj+hatk , then find the value of (veca xx vecb)*(veca xx vec c) .

If veca=hati+2hatj-hatk, vecb=2hati+hatj+hatk and vecc=5hati-4hatj+3hatk then find the value of (veca+vecb).vecc .

If veca=hati+hatj+hatk, vecb=hati-hatj+hatk, vec c=hati+2hatj-hatk , then the value of |(veca*veca,veca*vecb, veca*vecc),(vecb*veca, vecb *vecb,vecb*vecc),(vec c*veca, vec c*vec b,vec c*vec c)| is equal to :

If veca=hati+hatj+hatk, vecb=hati-hatj+hatk, vec c=hati+2hatj-hatk , then the value of |(veca*veca,veca*vecb, veca*vecc),(vecb*veca, vecb *vecb,vecb*vecc),(vec c*veca, vec c*vec b,vec c*vec c)| is equal to :

If veca=hati-2hatj+3hatk, vecb=2hati+hatj-2hatk, vec c=3hati+2hatj+hatk , find veca xx (vecb xx vec c)

If veca=hati-2hatj+3hatk, vecb=2hati+hatj-2hatk, vec c=3hati+2hatj+hatk , find veca*(vecb xx vec c) .

If veca=hati-2hatj+3hatk, vecb=2hati+hatj-2hatk, vec c=3hati+2hatj+hatk , find (veca xx vecb)xxvec c

If veca=hati-2hatj+3hatk and vecb=-2hati+hatj-2hatk , then the value of |veca xx vecb| is -

If veca=2hati+3hatj-hatk, vecb=3hati+5hatj+2hatk, vec c= -hati-2hatj+3hatk , verify that veca xx (vecb xx vec c)=(veca*vec c)vecb-(veca*vecb)vec c
