Question 118255
5/1+i write expression as complex number in standard form
:
Multiply by the conjugate of the denominator over itself
{{{5/((1+i))}}} * {{{((1-i))/((1-i))}}} = {{{(5(1-i))/((1 - i^2))}}} = {{{(5(1-i))/((1 - (-1)))}}} = {{{(5(1-i))/((1 + 1))}}} = {{{((5-5i))/2}}}
or
{{{5/2}}} - {{{5/2}}}i
