#### Explanation:

We'll call the given vector

The magnitude of a vector is given by

#|vecA| = sqrt((A_x)^2 + (A_y)^2) = sqrt(5^2 + 6^2) = color(blue)(ulbar(|stackrel(" ")(" "7.810" ")|)#

Vectors in the notation **unit vectors**, with the unit vector

#< 5,6 > = color(blue)(ulbar(|stackrel(" ")(" "5hati + 6hatj" ")|)#
