`\color{green}"The following steps explain How to handle a complex power"`
`x^{a+ib}=x^{a}.x^{ib}=x^{a}.(e^{log(x)})^{ib}because x=e^{log(x)}`
`=x^a.e^{ib.log(x)}=x^{a}[cos(b.log(x))+isin(b.log(x))]`  (by de Moivres theorem)
In the above result put a=0 and b=1 results in`x^i=[cos(log(x))+isin(log(x))]`
