**If k= 7i-3j+2k and L= 4i+5j-3k, calculate the magnitude of k and L, the magnitude of K + L and the mag of k-l? - ls mag pictures**

Magnitude of a vector is determined by the square root of the sum of the squares of the component vectors.

[K] = sqrt (7 ^ 2 +3 ^ 2 +2 ^ 2) =?

[L] = sqrt (4 ^ 2 +5 ^ 2 +3 ^ 2) =?

The sum of two vectors is obtained by adding ingredients.

[K + L] = (sqrt (7 +4) ^ 2 + (-3 +5) ^ 2 + (2-3) ^ 2)

To subtract a vector, to add your components with a minus sign.

[K - L] = (root (7-4) ^ 2 + (-3-5) ^ 2 + (2 +3) ^ 2)
