\[\frac{ 2+\sqrt{3i} }{ 5-4i }\]
rationalize it
\[\large{\frac{{(2+\sqrt{3i})}(5+4i)}{(5-4i)(5+4i)}}\]
can you multiply them and simplify ? @ArkGoLucky ?
Yeah I did that but the square root 3i is still on top and I can't rid of it

there are still 4 unlike terms on top so nothing simplifies
\[\large{\frac{(10+8i+5\sqrt{3i}+4i\sqrt{3i})}{9}}\]
that's enough simplification @ArkGoLucky
it is in the simplified form now
except it's 41 not 9

25-(4i)^2 = 25-(16(-1)) = 25+16= 41 oops sorry :P
but don't I need to put it into the a+bi form
answer given?
can u put that in a+b(sqrt{-1}) ? : P
sorry I read the problem wrong. It is much simpler. i is not under the square root. it's \[\sqrt{3}i\] thanks for your help anyways
