Let veca = 4hati + 5hatj - hatk, vecb = hati- 4 hatj + 5 hatk and vec c = 3hati + hatj- hatk. Find a vector vecd which is perpendicular to both vec a and vecb and satisfying vecd .vecc=21

If vec a=3hati-hatj+4hatk, vecb=2hati+3hatj-hatk and vec c=-5hati+2hatj+3hatk , then vec a.(vecb xx vec c) is

If two vectors are given as veca = hati - hatj + 2hatk and vecb = hati + 2hatj+hatk , the unit vector perpendicular to both vec a and vec b is

If two vectors are given as veca = hati - hatj + 2hatk and vecb = hati + 2hatj+hatk , the unit vector perpendicular to both vec a and vec b is

If veca = 3hati - hatj - 4hatk , vecb = -2hati + 4hatj - 3hatk and vec c = hati + 2hatj - hatk then |3veca - 2vec b + 4vec c | is equal to
