If →x is a vector in the direction of (2,−2,1) of magnitude 6 and – InterviewSolution

1.	If →x is a vector in the direction of (2,−2,1) of magnitude 6 and →y is a vector in the direction of (1,1,−1) of magnitude √3, then \|→x+2→y\| is equal to
Answer» If $\to x$ is a vector in the direction of $(2, - 2, 1)$ of magnitude $6$ and $\to y$ is a vector in the direction of $(1, 1, - 1)$ of magnitude $\sqrt{3}$ , then $\| \to x + 2 \to y \|$ is equal to
