Answer:

#vec C=22i+21j+13k#

Explanation:

#"the cross product of two vector is given as :"#
#vec A=(a,b,c)#
#vec B=(d,e,f)#
#vec C=vec A X vec B#
#vec C=i(b*f-c*e)-j(a*f-c*d)+k(a*e-b*d)#
#"Thus:"#
#vec 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)#
#vec C=22i+21j+13k#
