Final answer:
The distance between z1=(8+3i) and z2=(5-7i) is approximately sqrt(109).
Step-by-step explanation:
To find the distance between two complex numbers, we use the distance formula:
d = |z2 - z1|
Let's plug in the given values for z1 and z2:
d = |(5-7i) - (8+3i)|
Subtract the real parts and the imaginary parts:
d = |(5-8) + (-7-3)i|
d = |-3 - 10i|
Use the Pythagorean theorem to find the magnitude:
d = sqrt((-3)^2 + (-10)^2)
d = sqrt(9 + 100)
d = sqrt(109)
So, the distance between z1 and z2 is approximately sqrt(109).
