vec C=22i+21j+13k→C=22i+21j+13k

Explanation:

"the cross product of two vector is given as :"the cross product of two vector is given as :
vec A=(a,b,c)→A=(a,b,c)
vec B=(d,e,f)→B=(d,e,f)
vec C=vec A X vec B→C=→AX→B
vec C=i(b*f-c*e)-j(a*f-c*d)+k(a*e-b*d)→C=i(b⋅f−c⋅e)−j(a⋅f−c⋅d)+k(a⋅e−b⋅d)
"Thus:"Thus:
vec C=i(5*11-11*3)-j(-3*11-(-3*4))+k((-3)*(-11)-5*4)→C=i(5⋅11−11⋅3)−j(−3⋅11−(−3⋅4))+k((−3)⋅(−11)−5⋅4)
vec C=i(55-33)-j(-33+12)+k(33-20)→C=i(55−33)−j(−33+12)+k(33−20)
vec C=22i+21j+13k→C=22i+21j+13k
