    I would actually consider those two equal.

    Maybe what you're talking about is something like:

    -3^{4} versus (-3)^{4}

    In the first one, the negative is not grouped with the 3, so it it calculated by taking 3^4, then multiplying by -1. In the second one, the negative is included in the power calculation.
