Question 704657: The problem asks to simplify and express this expression in a+bi form:
+7+sqrt%28+-75+%29-2+sqrt%28+-147+%29-3i%5E50%2B6i%5E692+
I know that i^50 equals one and i^692 equals i so I got the problem down to
+7+sqrt%28+-75+%29-2+sqrt%28+-147+%29-3%2B6i+
but I don't know what to do next. Thank you for your help!

+7+sqrt%28+-75+%29-2+sqrt%28+-147+%29-3i%5E50%2B6i%5E692+

i%5E50+=-1
i%5E692=1
7%2A5%2Asqrt%28-3%29+-2%2A7%2Asqrt%28-3%29-3%28-1%29%2B6%2A%281%29
21%2Asqrt%28-3%29i%2B9
