Given:  $KA=\frac{{{{\left({3+2}\right)}^2}\times{{\left({0.05}\right)}^2}}}{{{{\left({7.3-2.3}\right)}^4}\times{{10}^{-5}}}}$

$KB=\frac{{\sqrt {{{\left({-10}\right)}^4}}+3\sqrt{12}-2\sqrt {27} }}{{\left({\sqrt{18}-\sqrt 8}\right)\left({\sqrt {18}+\sqrt 8 }\right)}}$

$KC=\frac{{16}}{2}+\frac{1}{{1-\frac{1}{{\sqrt 4}}}}$

and KD = 20% of 50.

Verify that A,B,C, & D belong to the same circle of center K.
