i%5E%282i%29+=0.0432139183
since i%5E%282i%29+=%28+i%5E2%29%5Ei, and
%28i%5E2%29%5Ei+=%28+-1%29%5Ei which is equal to
%28+-1%29%5Ei=0.043213918263772249774417737171728011275728109810633082980719 or, rounded 0.0432139183 which is a rational number because it could be written in a form p%2Fq as 432139183%2F10000000000
so, i%5E%282i%29+=0.0432139183 is a rational number
