## Homework Statement

Simplify √(53 - 8√15)

## Homework Equations

Numbers can be represented as √a - √b

## The Attempt at a Solution

I had tried to make in an equation where the 2 expressions were equal, but after squaring both sides, I didn’t really know what to do.

I had also tried to use something like making a perfect square, and I did get a number, though it was much longer and more complicated, and I don’t think that’s right.

Now I’m a bit lost, and I’m not sure how to use the √a - √b that the teacher gave us.

Thanks!
