真是超級簡單
e)None of the above
As x is a pure real number, but y only with imaginary part.
0 x6 J' b, h5 G$ j1 T# a0 b! YSo if want to compare these two numbers, it should compare there magnitude.
: l) K5 o& b  ]. o2 |1. x -> 0+0i3 G; x& L& i: L  U1 J  V
2. y -> 0+1i
! l) ~3 x2 V8 I0 v: \
6 l, ?. D7 e* U. kMagnitude of x is |√(0^2 +0^2)| = 00 T+ R( {/ x2 E0 @& H. E" k
Magnitude of y is |√(0^2+1^2)| = 1
$ _9 h; E* q, z) l+ mTVBNOW 含有熱門話題,最新最快電視,軟體,遊戲,電影,動漫及日常生活及興趣交流等資訊。! E/ ~, _1 l) Z& C' A
So, the magnitude of y >x
其實唔知啱唔啱,我都係估吓估吓咋
