To find 3u - 5v, you need to multiply each vector by their respective scalar and then subtract the second vector from the first.

Step 1: Multiply vector U by 3
3U = 3*(2, 4, -5) = (6, 12, -15)

Step 2: Multiply vector V by 5
5V = 5*(1, -6, 9) = (5, -30, 45)

Step 3: Subtract 5V from 3U
3U - 5V = (6, 12, -15) - (5, -30, 45) = (1, 42, -60)

So, 3u - 5v = (1, 42, -60).
