Answer:
3.605
Step-by-step explanation:
D=
- (6-3)2+(5-7) 2
- (3)2+(-2)2
- (9+4)
- (13)
- = 3.60551
or 3.6
or 3.605

Answer: complex equations has n number of solutions, been n the equation degree. In this case:
Step-by-step explanation:
I start with a variable substitution:
Then:
Solving the quadratic equation:
Replacing for the original variable:
or
Remembering that complex numbers can be written as:
Using this:
Solving for the modulus and the angle:
The possible angle respond to:
Been "RAng" the resultant angle, "Ang" the original angle, "n" the degree of the root and "i" a value between 1 and "n"
In this case n=4 with 2 different angles: Ang = 45º and Ang = 315º
Obtaining 8 different angles, therefore 8 different solutions.
