Q
Q: If M = (2, 2, 2) and N = (3, 3, 3), what is M · N?
Solution: M · N = 2*3 + 2*3 + 2*3 = 6 + 6 + 6 = 18.
Steps: 5
Step 1: Identify the components of vectors M and N. M has components (2, 2, 2) and N has components (3, 3, 3).
Step 2: Multiply the corresponding components of M and N. This means you will multiply the first component of M by the first component of N, the second component of M by the second component of N, and the third component of M by the third component of N.
