. Given a vector $x ∈ R_{n}$ , we define $||xi||=1$ , $P_{n}(i)=1....n$ $|x_{i} | = |x_{1}| + |x_{2}| + |x_{3}| +.........|x_{n}| $and$ P_{n}( i) =1..........n$ $\sqrt{|x_{1}|^{2}+|x_{2}|^{2}+|x_{3}|^{2}.......}$. ... in x. The indices of all true (and no false) statements are (i) . (For example, if you think statements (a) and (b) are true and the rest false, write down (a),(b)' as your answer).
