Answer:

Explanation:
To find the distance between two complex numbers, we use the formula:
distance = |z1 - z2|
where z1 and z2 are the complex numbers.
In this case, z1 = 6 + 5i and z2 = -2 + 4i, so we have:
distance = |(6 + 5i) - (-2 + 4i)|
= |8 + i|
= sqrt(8^2 + 1^2)
= sqrt(65)
Therefore, the distance between 6+5i and -2+4i is sqrt(65).
