  1. Use Vector Magnitude Formula: First, we need to use the formula for the magnitude of a vector, which is a=a12+a22|\mathbf{a}| = \sqrt{a_1^2 + a_2^2} where a1a_1 and a2a_2 are the components of vector a\mathbf{a}. So, we plug in the values from vector a=([2],[3])\mathbf{a} = ([2], [3]) into the formula. This gives us a=22+32|\mathbf{a}| = \sqrt{2^2 + 3^2}.
  2. Plug in Values: Now, we calculate the squares of the components.\newlineThis gives us a=4+9|a| = \sqrt{4 + 9}.
  3. Calculate Squares: Next, we add the squares together.\newlineThis gives us a=13\lvert a \rvert = \sqrt{13}.
  4. Add Squares: So, the magnitude of vector aa is 13\sqrt{13}, which is one of the options given.
