1. ## exponents differences

could you please explain to me what the difference is between (3)^-4 and
3^-4

Thanks!

2. 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.
