Question 1208825
<pre>

{{{i^(-23)}}}{{{""=""}}}{{{i^(-24+1)}}}{{{i^(-24)*i^1}}}{{{""=""}}}

{{{i^(2*(-12))*i}}}{{{""=""}}}{{{(i^2)^(-12)*i}}}{{{""=""}}}{{{(-1)^(-12)*i}}}{{{""=""}}}{{{i}}} since -1 to any even power is +1

For the other one, if you meant {{{(1 + i)^3}}} then

{{{(1 + i)^3}}}{{{""=""}}}{{{1+3i+3i^2+1^3}}}{{{""=""}}}{{{1+3i+3(-1)+i^2*i}}}{{{""=""}}}
{{{1+3i-3+(-1)i}}}{{{""=""}}}{{{-2+2i}}}
