    Inequations

    This is my first post in this forum, and I sincerely hope to be doing the right thing, posting in the right section. Here it goes.

    sqrt (x+2) > 0

    and

    (3/2) log (x-2)<0

    Thank you.

    \left(\sqrt{x+2}\right)^2 > 0^2

    x+2 > 0

    x > -2

    actually, \sqrt{x+2}>0 is true as long as the radicand is well defined, so it's just x>-2 and there's no need to square.

    that's just \log(x-2)<0.

    we require that 0<x-2<1.

    I thought it was like this.
