Question 1001235

{{{(6+2i)/(1+7i)}}}


={{{((6+2i)(1-7i))/((1+7i)(1-7i))}}}


={{{(6-42i+2i-14i^2)/((1^2-(7i)^2))}}}


={{{(6-40i-14(-1))/(1-49(-1))}}}


={{{(6-40i+14)/(1+49)}}}


={{{(2cross(0)-4cross(0)i)/5cross(0)}}}


={{{(2-4i)/5}}}


={{{2/5-4i/5}}}=>the result in the form {{{a+bi}}}


 the real number a  {{{a=2/5}}}

the real number {{{b =-4/5}}}
