Today I will go through a question involving recurring square roots.
First, I will reveal a neat trick using substitution to solve this problem. Then we follow with solving its generic extension.
Finally, I will provide an alternative solution involving geometric sum.
And we shall see how the proof of the formula of infinite geometric sum can be derived by our trick.
