As x is a pure real number, but y only with imaginary part.tvb now,tvbnow,bttvb. t; c* W( S3 _: }, R5 y( w
So if want to compare these two numbers, it should compare there magnitude.: R$ l# a, g- q' w# R- T0 S
1. x -> 0+0i

Magnitude of x is |√(0^2 +0^2)| = 0tvboxnow.com1 o y0 a" P, V6 ^6 q/ v; j
Magnitude of y is |√(0^2+1^2)| = 10 B: {, G4 T" V0 o

So, the magnitude of y >x |
