    2\[(-2)^{-3*24}=(-2)^{72}\]

    I think that should be \[(-m)^{-3}n\] Yes?

    what exactly is your question, what are you supposed to find?

    First thing to remember is that \[x^{-m} = \frac{1}{x^m}\]If we rewrite the expression in that fashion, we get \[\frac{n}{(-m)^3} = \frac{-24}{(-2)^3}\]Can you evaluate that?

    \[(-2)^3 = (-2)*(-2)*(-2)\]

    Did someone say it was? \[\frac{-24}{(-2)*(-2)*(-2)}\]What does the expression on the bottom equal?

    \[\frac{ -24 }{ -2*-2*-2 }=\frac{ -24 }{ -8 }---> -A*-A*-A=-A\]

    and \[\frac{ -24 }{ -8 }=\frac{ 24 }{ 8 }=3\] LOL

    Another way of looking at this is \[\frac{-24}{(-1*2)^3} = \frac{-24}{(-1)^3*2^3}\]\(-1^n = -1, n\) odd so we have \[\frac{-24}{-1*2^3} = \frac{-24}{-8} = 3\]

    We can factor out that -1 because \[(ab)^n = a^nb^n\]
