    Negative Exponents

    Evaluate:

    (3^-2 + 4^-1)^-2

    I got 1296/97

    can anyone tell me if i'm right?

    by the way guys, how do i use latex, because the matrix that i used to click on when posting the thread, that created the latex brackets is no longer there.

    thanks.

    I didn't do it out on paper but just used a CAS and got 1296/169. I could do it on paper, but it might be more useful if you simply checked your work, or posted some of it for us to check.

    Since the recent forum upgrade, the LaTeX modules are not fully functional yet, and the admins are working on it.

    Nice Lamborghini by the way.
