真是超級簡單
e)None of the above
As x is a pure real number, but y only with imaginary part.
8 {) y1 A5 @9 D2 D0 G) \So if want to compare these two numbers, it should compare there magnitude.

Magnitude of x is |√(0^2 +0^2)| = 0
( p8 {5 s$ [2 H. Y: D* A4 gMagnitude of y is |√(0^2+1^2)| = 1
' ?# ^7 G% v2 d& g2 B9 t4 t( I5 e2 {) O& A: x
So, the magnitude of y >x
其實唔知啱唔啱,我都係估吓估吓咋
