SUMMARY
The proof of the equation |z1|^2/|z2|^2 = |z1/z2|^2 is established using the properties of complex numbers. By defining z1 as a + jb and z2 as l + jm, the left-hand side (LHS) is calculated by taking the modulus, resulting in a^2 + b^2. The right-hand side (RHS) is derived by rationalizing the numerator and denominator of z1/z2, leading to the conclusion that LHS equals RHS through separation of real and imaginary parts.
