    High School What Is the Argument of j to the Fourth Power?

    okie ... one attempt as i see it ... argument of j is pie/2 ... so argument of j^2 will be pie square/ 4 and so on ... is it right?

    Why does the argument change in solving z^3 = j using DeMoivre's theorem?

    q. find all the solution of equation z^3= j Attempt okie now we know we have its argument as pie/2 but my friend did this and he placed the argument of it as THETA + 2*pie*k/ n i want to ask first why the argument change ? second , i thought in demoivers theorem we...
