Question 179517:  1.(-4+2i)+(6-3i)
 
2.6√-12
 
3.√-8*√-32
 
4.i^65
 
 
5.i^89 
 Answer by stanbon(75887)      (Show Source): 
You can  put this solution on YOUR website! 1.(-4+2i)+(6-3i) = 2 -i 
--------------------------------  
2.6√-12 = 6*2sqrt(3)i 
------------------------- 
3.√-8*√-32 = 2sqrt(2)i * 4sqrt(2)i = 8*2*(-1) = -16 
---------------------------  
4.i^65 = i^64 * i = 1*i = i 
---------------------------------- 
5.i^89 = i^88 * i = 1*i = i 
===============================
