As x is a pure real number, but y only with imaginary part.' ]9 N8 l" j& r: Q
So if want to compare these two numbers, it should compare there magnitude.5.39.217.779 d0 Y7 s" b7 s. \" B
1. x -> 0+0i

Magnitude of x is |√(0^2 +0^2)| = 0# x( h) {& T6 t& {
Magnitude of y is |√(0^2+1^2)| = 15.39.217.77* n) L( k4 O4 m8 x, M

So, the magnitude of y >x |
