Assuming the subscript was intended and unnecessary
1-1%2Fk=0.9
-1%2Fk=0.9-1
1%2Fk=0.1
k=10

If that's matrix%281%2C3%2C+1+-+1%2Fk%5E2%2C+%22=%22%2C+.9%29, 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 k%5E2, 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?
