Simplify sqrt(p^2) solve this. i will give whoever solves this points.

It's a bit of a trick question.  The principal square root of a real number, as indicated by the radical sign, is never negative. So if p is negative we'll get -p as the result.  We write this with absolute value:

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
