Magnitude of $$$\left\langle i a g h m n r s t^{2} e^{e i n o r s^{2}}\right\rangle$$$
Your Input
Find the magnitude (length) of $$$\mathbf{\vec{u}} = \left\langle i a g h m n r s t^{2} e^{e i n o r s^{2}}\right\rangle$$$.
Solution
The vector magnitude of a vector is given by the formula $$$\mathbf{\left\lvert\vec{u}\right\rvert} = \sqrt{\sum_{i=1}^{n} \left|{u_{i}}\right|^{2}}$$$.
The sum of squares of the absolute values of the coordinates is $$$\left|{i a g h m n r s t^{2} e^{e i n o r s^{2}}}\right|^{2} = a^{2} g^{2} h^{2} m^{2} n^{2} r^{2} s^{2} t^{4}$$$.
Therefore, the magnitude of the vector is $$$\mathbf{\left\lvert\vec{u}\right\rvert} = \sqrt{a^{2} g^{2} h^{2} m^{2} n^{2} r^{2} s^{2} t^{4}} = t^{2} \left|{a g h m n r s}\right|.$$$
Answer
The magnitude is $$$t^{2} \left|{a g h m n r s}\right|$$$A.
