Question

How do you solve this complex number equation?

Answer 1

\[|z ^{2}-9i|=16|\frac{ 1 }{ i }-\frac{ 9 }{ z ^{2} }|\]

Answer 2

\(\LARGE\color{blue}{ \bf ±(z^2-9i)=16(\frac{1}{i}-\frac{9}{z^2}) }\)makes sense to re-write it like this, right?

Answer 3

but it's modulus

Answer 4

Wait, I thought it's absolute value.

Answer 5

No sadly xD

Answer 6

dang:) I actually never learned that. surprisingly. I solved even higher level problems like calc 1,2,3 but I have some empty spaces in my knowledge -:(
