properties of complex numbers ?

Hi buddy
Good noon
Here is your answer
ListenProperties of Complex Numbers
Properties of Complex NumbersIf x, y are real and x + iy = 0 then x = 0, y = 0.
Properties of Complex NumbersIf x, y are real and x + iy = 0 then x = 0, y = 0.If x, y, p, q are real and x + iy = p + iq then x = p and y = q.
Properties of Complex NumbersIf x, y are real and x + iy = 0 then x = 0, y = 0.If x, y, p, q are real and x + iy = p + iq then x = p and y = q.Like real numbers, the set of complex numbers also satisfies the commutative, associative and distributive laws i.e., if z1, z2 and z3 be three complex numbers then,
Hope it help you

Explanation:
The law of commutativity: a + b = b + a; ab = ba, for all a, b ∈ R.
II The law of associativity: (a + b) + c =
a + (b + c); (ab)c = a(bc), for all a, b, c ∈ R.
III The law of distributivity: (a + b)c = ac + bc, for all a, b, c ∈ R.
IV The law of identity: a + 0 = a; a1 = a, for all a ∈ R.
V The law of additive inverse: Given any a ∈ R, there exists a unique x ∈ R such that
a + x = 0.
VI The law of multiplicative inverse: Given a ∈ R, a 6= 0, there exists a unique x ∈ R
such that ax = 1.
Furthermore, there is a total ordering ‘<’ on R, compatible with the above arith-
metic operations, which makes R into an ordered field. Recall that < is a total ordering
means that:
VII given any two real numbers a, b, either a = b or a < b or b < a.
The ordering < is compatible with the arithmetic operations means the fo
