Answer:

As I understood

Explanation:

Let #vecA=A_xhati+A_yhatj+A_zhatk# and
#vecB=B_xhati+B_yhatj+B_zhatk#

To find (#vecA-vecB#)
Inserting values of both the vectors in terms of unit vectors we get

#vecA-vecB=(A_xhati+A_yhatj+A_zhatk)-(B_xhati+B_yhatj+B_zhatk)#
#=>vecA-vecB=(A_x-B_x)hati+(A_y-B_y)hatj+(A_z-B_z)hatk#
