Question 491856
I think you mean (4+7i)/(5+5i)
------------
There's nothing to solve, it's not an equation.
You can rationalize the denominator, ie, make it a real number.
(4+7i)/(5+5i) = (4+7i)/5(1+i)
Multiply the NUM and DEN by the conjugate of 1+i, which is 1-i
{{{(4+7i)/5(1+i) = (4+7i)(1-i)/(5(1+i)(1-i))}}}
= {{{(4+7 +3i)/(5*2)}}}
= {{{(11+3i)/10}}}
