1)make Compare between z,w

2)find z!

3)IzI=sqart root (z^2)

or IzI=sqart root(zz')

IzI=sqart root (z^2)=sqart root(zz')

4) Compare between 1,i

5) i!=????

2. Is "!" supposed to be the factorial? It's only defined for positive integers, not complex numbers.

3. If, by ', you mean "complex conjugate", then [itex]|z|= \sqrt{zz'}[/itex] which is NOT the same as [itex]\sqrt{z^2}[/itex] unless z is real.

I am unaware of any definition of "less than" or "greater than" concerning complex numbers.

1. What do you mean by "compare"? Find the difference? Absolute value of difference?

Neither. The field of complex numbers is NOT an "ordered field".I mean

Z<W OR W<Z
