|(3 + 4*i*) - (5 + 6*i*)| = |-2 - 2*i*| = 2√(2) or √(8)

|(9 + 5*i*) - (7 - 2*i*)| = |2 + 7*i*| = √(53)

|(11 + 11*i*) - (8 + 8*i*)| = |3 + 3*i*| = 3√(2) or √(18)

|(5 - 5*i*) - (5 + *i*)| = |-6*i*| = 6

|(-5 + 5*i*) - (-4 + 4*i*)| = |-1 + *i*| = √(2)

Note: Considering **a + b i**, if you see a minus sign instead of a plus sign between
