真是超級簡單
e)None of the above
As x is a pure real number, but y only with imaginary part.tvb now,tvbnow,bttvb# i6 k5 |( r3 V
So if want to compare these two numbers, it should compare there magnitude.

Magnitude of x is |√(0^2 +0^2)| = 0- i* B" q& m+ `. a
Magnitude of y is |√(0^2+1^2)| = 1公仔箱論壇; Q' j1 {+ f" _4 `, O7 S$ R5 L7 X

其實唔知啱唔啱,我都係估吓估吓咋
