I'm having trouble with infinite surds.
I understand that as approches infinity approaches zero.
I understand that the limit of the sequence is the exact value of the infinite surd.
I also know how to solve the surd by setting it equal to x and using quadratics.
But what I don't understand is how to connect any of it. I can't explain how to get from to the exact value.
In other words, I'm at point A and I know where point B is, I just don't know how to get there.
