真是超級簡單
e)None of the above
As x is a pure real number, but y only with imaginary part.
  ?. V% F: ]2 H! lSo if want to compare these two numbers, it should compare there magnitude.5 [9 J& G2 I! l  d6 L
1. x -> 0+0itvb now,tvbnow,bttvb8 U* _. S. |1 C/ M
2. y -> 0+1i
2 Z3 B: {' p% G( _5 L, z0 W, t7 B4 g
Magnitude of x is |√(0^2 +0^2)| = 0
7 K6 [# Q0 ~9 A# W1 A( R; K" Vtvb now,tvbnow,bttvbMagnitude of y is |√(0^2+1^2)| = 15.39.217.77:8898  _) g! }. h- P5 Q( E& m. y0 w+ A

3 z$ a! z  X, ?! a) mSo, the magnitude of y >x
其實唔知啱唔啱,我都係估吓估吓咋
