Does anyone know what it means when you have a bracket to the power of a " + "?

Does it make everything within the bracket positive?

I think you need to clarify your question. What do you mean by a bracket?

e^(i*pi)
I don't understand what you mean? Do you have an example?

A positive exponent (which I'm guessing what you mean) means you multiply the base by itself on the exponent time. For example $x^2 = x \cdot x$. Contrast with a negative exponent which means taking the reciprocal $x^{-2} = \dfrac{1}{x \cdot x}$
