Posted by on .

express the complex number in standard form(that is like a+bi)


1/2+i



2+i/2-i

  • precalc - ,

    rationalize the denominator. I will do one:

    (2+i)/(2-i)= 2+i)(2+i)/(2-i)(2+i)=

    (2+i)^2/(2-i^2)= (4+4i+i^2)/3
    you can complete it.

  • precalc - ,

    so is that the final answer

  • precalc - ,

    os is the final answer 8i+i^3/3

  • precalc - ,

    (2+i)/(2-i)
    =(2+i)(2+i)/((2+i)(2-i))
    =(4+4i+i²)/(2²-i²)
    =(4+4i-1)/(4-(-1))
    =(3+4i)/5

    You can proceed along the same lines for the first problem.
