Prove that `hatixx(vecaxxveci) + hatjxx(vecaxxvecj) + hatkxx(vecaxxveck)=2veca`

Prove that hati xx(vecaxxveci)+hatjxx(vecaxxvecj)+hatkxx(vecaxxveck)=2veca

Prove that hati xx(vecaxxveci)+hatjxx(vecaxxvecj)+hatkxx(vecaxxveck)=2veca

Prove that hati xx(vecaxxveci)+hatjxx(vecaxxvecj)+hatkxx(vecaxxveck)=2veca

For any vector veca prove that hatixx(vecaxxhati)+hatjxx(vecaxxhatj)+hatkxx(vecaxxhatk)=2veca

Prove that : vecixx(vecaxxveci)+vecjxx(vecaxxvecj)+veckxx(vecaxxveck)=vec(2a)

For an vector veca the value of hatixx(vecaxxveci)+hatjxx(vecaxxhatj)+hatkxx(vecaxxveck) , is

Show that vecixx(vecaxxveci)+vecjxx(vecaxxvecj)+kxx(vecaxxveck)=2veca for any vector a.

If veca is any vector and hati,hatj and hatk are unit vectors along the x,y and z directions then hatixx(vecaxxhati)+hatjxx(vecaxxhatj)+hatkxx(vecaxxveck)= (A) veca (B) -veca (C) 2veca (D) 0

If veca is any vector and hati,hatj and hatk are unit vectors along the x,y and z directions then hatixx(vecaxxhati)+hatjxx(vecaxxhatj)+hatkxx(vecaxxveck)= (A) veca (B) -veca (C) 2veca (D) 0

Prove that (veca-vecb)xx(veca+vecb)=2(vecaxxvecb) .
