1. The problem statement, all variables and given/known data Find the modulus and argument of z=((1+2i)^2 * (4-3i)^3) / ((3+4i)^4 * (2-i)^3 2. Relevant equations mod(z)=sqrt(a^2+b^2) 3. The attempt at a solution In order to find the modulus, I have to use the formula below. But I'm struggling with finding out how to put the equation in the formula: I have attached a photo of how I did it so far. But unfortunately, it does not give sence.
