Answer 1

please answer...

Answer 2

that one too if you guys would be so kind

Answer 3

√-49/(3+4i)-(2-5i)

Answer 4

A complex number must have a real and imaginary part.

It can be in the form: a + bi

Answer 5

conjugate of \(a+bi\) is \(a-bi\) reflected about the real axis
useful because
a) if \(a+bi\) is a zero of a polynomial with real coefficients then so is \(a-bi\)

b) also it is always true that \((a+bi)(a-bi)=a^2+b^2\) a real number, so you use it do divide
