If `veca=hati+hatj+hatk, vecb=2hati-hatj and vecc=3hatj+hatk` then verify the following: `(veca+vecb).(veca-vecb)=a^2-b^2`.

If veca=hati+hatj+hatk, vecb=2hati-hatj and vecc=3hatj+hatk then verify the following: veca.(vecb+vecc)=veca.vecb+veca.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=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 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=7hati+3hatj-6hatk , vecb=2hati+5hatj-hatk and vecc=-hati+2hatj+4hatk . Find (veca-vecb)xx(vecc-vecb) .

If veca=2hati+3hatj+4hatk,veca.vecb=2 and vecaxxvecb=2hati-hatk , then vecb is

Let veca=hati-hatj+hatk, vecb=2hati+hatj+hatk and vecc=hati+hatj-2hatk , then the value of [(veca, vecb, vecc)] is equal to

If veca = (hati - 2hatj), vecb = (2hati - 3hatj) and vecc = (2hati + 3hatk) , find (veca + vecb + vecc) .

if veca=hati-hatj-3hatk, vecb=4hati-3hatj+hatk and vecc=2hati+hatj+2hatk, verify that vecaxx(vecb+vecc)=vecaxxvecb+vecaxxvecc
