Wow, this is what happens when there are too many square roots in an expression.

Maybe putting it in indices format would reduce the occurrence of careless mistakes .

Three, four, five, etc, will be hard to keep track.

Brackets too. That's why I prefer to use some [ ] sometimes instead of many ( )
