Are any of the following expressions are valid? First check the ranks and validity of the operations in the various expressions. If you see no problems, then use index notation to see whether the expression is correct. If an expression is invalid, you do not need to make it correct. a) V-(Vxy)= Vx(V•v) +V²v b) (vxw)·(y×w)= v²w²-(v•w)² c) V×X = 0 where X is the position vector

Please answer all 3 questions with details. 

Are any of the following expressions are valid? First check the ranks and validity of the
operations in the various expressions. If you see no problems, then use index notation to see
whether the expression is correct. If an expression is invalid, you do not need to make it correct.
a) V-(Vxv)= Vx(V• v) +V²y
b) (v×w)(v×w)=v²w²-(v•w)²
c) VxX = 0 where X is the position vector
