You can put this solution on YOUR website!
(1)
+1%2F%28+-8+-+5i+%29+
You can put the minus signs in front of the fraction
+-+1%2F%28+8+%2B+5i+%29+
Multiply top and bottom by +8+-+5i+
+%28-+1%2F%28+8+%2B+5i+%29%29%2A%28+%28+8+-+5i+%29+%2F+%28+8+-+5i+%29+%29+
----------------------------------
+%28+-1%2A%28+8+-+5i+%29%29+%2F+%28+64+%2B+40i+-+40i+%2B+25i%5E2+%29+
Note that +i%5E2+=+-1+
--------------------
+%28+-8+%2B+5i+%29+%2F+%28+64+-+25+%29+
------------------------
+%28+-8+%2B+5i+%29+%2F+39+ answer
----------------------
(2)
+i+%2F+%28+-2+-+8i+%29+
---------------
+-i+%2F+%28+2+%2B+8i+%29+
Multiply top and bottom by +2+-+8i+
--------------------------------
+%28-i+%2F+%28+2+%2B+8i+%29%29%2A%28+%28+2+-+8i+%29+%2F+%28+2+-+8i+%29+%29+
----------------------------------
+%28+-i%2A%28+2+-+8i+%29+%29+%2F+%28+4+%2B+16i+-+16i+-+64i%5E2+%29+
---------------------------
+%28+-2i+%2B+8i%5E2+%29+%2F+%28+4+%2B+64+%29+
-------------------------
+%28+-8+-+2i+%29+%2F+68+
----------------
+%28+-4+-+i+%29+%2F+34+ answer
-----------------------
This is all I have time for. You should have the idea now
