Question

A = 2^i - 5^j + 3^k and B = -4^i + 2^j + 6^k show that are perpendicular vectors​

Answer 1

Answer:

! ! !

Explanation:

to show that the vectors are perpendicular, the sum of the product of each dir must be 0

=2 x (-4) + (-5) x (2) + (6)x(3)

= -8 - 10 +18

= 0

HENCE THEY ARE PERPENDICULAR
