A) \[\sqrt{10}\]
B) \[\sqrt{8}\]
C) \[\sqrt{\frac{17}{2}}\]
D) \[\sqrt{7}\]
Correct Answer: D
Solution :
\[z=x+iy\] \[A\text{/}Q\,\,\,|x|+|y|\,\,=4\] Min. \[|z|\,=2\sqrt{2}\] Max. \[|z|\,=\,\,4\] so \[|z|\,\in \,\,\left[ 2\sqrt{2},\,4 \right]\] \[\Rightarrow \,\,\,|z|\,\ne \,\,\sqrt{7}\]You need to login to perform this action.
