6D.5 part c

I am having trouble matching an answer to the key. I keep getting 4.64, which I realize is twice as much as the correct answer 2.32. Could anyone walk me through how they set up this problem?

My ICE table for (CH3)3N (aq) +H2O (l) <-> OH- (aq) + (CH3)3NH (aq) is
0.35 0 0
-x +x +x
0.35-x x x

and I got Kb=6.5e-5=x^2/0.35. When I solved for x, I got 2.3e-5, but when I took the -log of that value I got 4.64 instead of the listed answer 2.32. What am I doing wrong? Please let me know and thanks!

Nevermind, I just realized it's because I forgot to take the square root of what my x^2 was equal to. My bad!
