If bar(x)=(1,1,-1),bar(y)=(-1,2,2) and bar(z)=(-1,2,-1) then the unit victor perpendicular to both bar(x)+bar(y) and bar(y)-bar(z) is …………

If bar(a)=(2,1,-1),bar(b)=(1,-1,0),bar(c)=(5,-1,1) then the unit vector parallel to bar(a)+bar(b)-bar(c) , but in opposite direction is

If bar(a)=(2,1,-1),bar(b)=(1,-1,0),bar(c)=(5,-1,1) then the unit vector parallel to bar(a)+bar(b)-bar(c) , but in opposite direction is

If bar(a)=(2,1,-1),bar(b)=(1,-1,0),bar(c)=(5,-1,1) then the unit vector parallel to bar(a)+bar(b)-bar(c) but in the opposite direction is
