Dividing: Write the expression as a complex number in standard form
1) 2+5i/5+2i
2) 6i√2/6+i√2
for the first one I solved it and I only got this far: 10+21i10i^2/254i^2

Steve,
Remember that i^2 = 1
254i^2 = 25+4 = 29
10 + 21i  10i^2 = 10 + 21i + 10 = 20 + 21i
So, you have (20 + 21i)/29 = 20/29 + 21/29 i
