Evaluate the expression (sqrt(-5))/(sqrt(-1)sqrt(-7)) and write the result in the form a+bi.
--------------------
(sqrt(-5))/(sqrt(-1)sqrt(-7))
---
= sqrt(-5)/(i*sqrt(7)i)
-----
= sqrt(5)i/(-sqrt(7))
---
= sqrt(35)i/(-7)
---
= 0 -(1/7)sqrt(35)i
------------------------
The real number a= 0
The real number b= (-1/7)sqrt(35)
