Question

Let A=10i + 12j -8k
B= 8i - 10j -12k
Find A. B
A*B

Answer 1

-952

Step-by-step explanation:

because when doting different letter's results into scalar quantity or in short it's one

Answer 2

The dot product of two vectors A and B is given by the formula A.B = Ax * Bx + Ay * By + Az * Bz. So, if A = 10i + 12j - 8k and B = 8i - 10j - 12k, then A.B = (10)(8) + (12)(-10) + (-8)(-12) = 80 - 120 + 96 = 56.
