This is why I should just shut my mouth when it comes to forums and math. No matter what answer you give there's always another question. I'll take a stab at it but I can tell you are trying to turn it into a real number by using an absolute value.
|z| = square root of (9x-7i)(9x-7i)
|z| = square root of 81x2-63xi-63xi+49
|z| = square root of 81x2-126xi+49
|z| = square root of (9x-21u)(9x-21u)
|z| = square root of 81x2-189xu-189xu+441
|z| = square root of 81x2-378xu+441
|z| = square root of 3/27x2-126xi+147
That's as far as I've gotten. I haven't done complex numbers in forever. I'll be sure to work on it and I'd appreciate it if you don't say the answer so I can keep working on it. I'm sure I'm on the wrong track anyways.

I won't. But I truly have no idea why I even post on here. I haven't had fun in the funhouse in a long ass time. I believe I shall ban myself from it actually. Uni is starting again in 11 days and I don't have any reason to even view this forum >.>
