Find the manitude of each vetcor, and write each vector as the sum of the unit vectors.
Choose either one
(2,6) or (4,5)
Thank you

The magnitude of each vector is found by taking the square root of the square of each component.
(2,6) = sqrt(2^2 + 6^2)
It is usually written as double bars.
The vector can also be expressed as the sum of scalar components multiplied by unit vectors. With i = (1, 0) and j = (0, 1), then (2, 6) = 2i + 6j.
