Question

Z1=-12-17i and z2=-6-12i find the distance between z1 and z2

Answer 1

`√(61)`

Explanation:

we use the distance formula just like in coordinate geometry.

difference in real axis: (-12--6)=-6

difference in complex axis: (-17--12)=-5

now use distance formula.

sqrt(36+25)=sqrt(61) is the distance between them.
