If that's , then the other person's answer that k = 10 is WRONG!!!
As a matter of fact, if the above is what you meant, and if you're looking for , then that's equal to 10.
If you need a correct answer, you need to present your problem better than you did here. In other words, if it's what I stated above,
then you should've written: 1 - (1/k^2) = .9, and also k^2, instead of k2. Do you understand what I'm saying?
