As x is a pure real number, but y only with imaginary part.5.39.217.77/ [- Y) a8 ~; L* ~$ l' Q! k& x
So if want to compare these two numbers, it should compare there magnitude.5.39.217.779 b8 f* E$ T, Y
1. x -> 0+0i$ w6 Y* c, K4 t1 I5 F4 |. L
2. y -> 0+1i5.39.217.77' Z, g S# }- d; r. u! ~
5.39.217.77& B& r$ Y/ b4 Y% U
Magnitude of x is |√(0^2 +0^2)| = 0. d* \2 x. P. s/ L+ O3 U+ o; R% M
Magnitude of y is |√(0^2+1^2)| = 1) l; f/ @$ Q. p: X ]
" f1 A6 N4 q2 f0 y
So, the magnitude of y >x |
