(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] calculating complex number

1. The problem statement, all variables and given/known data

Calculate [tex]{i}^{\frac{3}{4}}[/tex]

2. Relevant equations

3. The attempt at a solution

I tried with

[tex]i=cos\frac{pi}{2}+isin\frac{\pi}{2}[/tex]

[tex]i^3=cos\frac{3pi}{2}+isin\frac{3\pi}{2}[/tex]

[tex]i^3=-i[/tex]

[tex]\sqrt[4]{i^3}=\sqrt[4]{-i}[/tex]

I don't know where I should go out of here. Please help!
