Given v = (2, -3, 4), find 3v.
Solution
Problem
Given v = (2, -3, 4), find 3v.
Step 1: Recall scalar multiplication.
To multiply a vector by a scalar, multiply every component of the vector by that scalar.
The vector is:
v = (2, -3, 4)
The scalar is 3.
Step 2: Multiply each component by 3.
3(2) = 6
3(-3) = -9
3(4) = 12
Step 3: Write the resulting vector.
3v = (6, -9, 12)
Therefore, 3v = (6, -9, 12).
Result
3v = (6, -9, 12)
