Please write in clean penmanship, thank you!

(1) For each of the following false statements give a counter-example (i.e. an example
set of vectors which demonstrate that the statement is false). You may, but do not
have to, reuse your example vectors.
(a) If v and w are any two vectors then || 7 – w || = || 7 || – || ||-
(b) If ở and w are any two non-parallel three dimensional vectors then there is
only one unit vector perpendicular to both 7 and w.
(c) If ở and w are any two three dimensional vectors then x w + w x ở.
