(1 point) Are the following statements true or false?
False 1. If $\vec{u}$ and $\vec{w}$ are any two vectors, then $||\vec{u} + \vec{w}|| = ||\vec{u}|| + ||\vec{w}||$.
True 2. ($\vec{i}$ × $\vec{j}$) ⋅ $\vec{k}$ = $\vec{i}$ ⋅ ($\vec{j}$ × $\vec{k}$).
True 3. The value of $\vec{v}$ ⋅ ($\vec{v}$ × $\vec{w}$) is always zero.
True 4. For any scalar c and any vector $\vec{v}$, we have $||c\vec{v}|| = c||\vec{v}||$.
