Ello.....frnds......solve this......sukriya☺️✌️✌️

Answer 1

Let unkown vector be a = xi + yj + zk
b = i+j-3k
c=i+3j-2k
d=2i +j+4k

A/Q  a.b = x + y -3z = 0
        a.c = x + 3y -2z = 5
        a.d = 2x+y+4z = 8

Now we can solve these 3 linear equations using determinant.
gives  x = 41/13         y = -14/13     z = 9/13

Hence vector a = 41/13 i - 14/13 j + 9/13 k
