A) \[2\sqrt{3},\,\,3\sqrt{3}\]
B) \[\,\,3\sqrt{3},\,-3\sqrt{3}\]
C) \[\sqrt{3},\,-\sqrt{3}\]
D) \[2\sqrt{2},\,-2\sqrt{2}\]
Correct Answer: B
Solution :
| [b] For zeroes \[{{z}^{2}}-27=0\] |
| \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{{z}^{2}}=27\Rightarrow z=\pm \sqrt{27}\] |
| \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,z=\pm 3\sqrt{3}\] |
