# Help concerning a simple operation

## The Attempt at a Solution

Consider the equation

$$1+A = (\sqrt{1 - B})^{-1}$$

A and B are just arbitrary constants.

If I wanted to square both sides, would that be

$$2 + A^2 = \frac{2}{1 - B}$$

or do I ignore the 1's and write it as

$$1 + A^2 = \frac{1}{1 - B}$$

Thanks! I am just young and wanted to know!

"Bumping" a thread in less than 24 hours is against forum rules. You should read the rules.

You math is all completely wrong. I have no idea how you got ANY of what you got.

EDIT: show the steps in how you got from one form to the next so we can see where you are going wrong.

well isn't

(something)^-1 = 1/(something)

or do you mean how we arrive at the first formula? That isn't important, there isn't a derivation, it's just an equation.

The right hand side of your final equation is correct, but the left hand side isn't.
