This is an oldie:  What's i^i, where i = sqrt(-1)?   Ans:  By Euler's formula, we know that e^pi i = -1.  Therefore e^(1/2) pi i = i, or e^-(1/2) pi = i^i = 0.20788.

Would you please type your entire math question the way it is presented in your book? Your description is not enough for anyone to answer you correctly. Thanks!

Umm... I think a "web math homework solver" doesn't exist. You could try getting Mathematica (i'm not discussing how you get the full version), it is a little complicated but it solves (if you know how to use it) all kinds of math problems.\n\nhttp://www.wolfram.com/

You can find a bunch of them in this website:\nhttp://www.mathpuzzle.com/
