How to simplify expressions with exponents.) Then the answer is: Why did I add the "for x not equal to 0" notation after the simplified fraction?

Because the original expression was not defined at x = 0 (since this would have caused division by zero in the second of the two original fractions). For the two expressions, the original one and the simplified one, to be "equal" in technical terms, their domains have to be the same; they have to be defined for the same x-values. Since the simplified fraction, 3x/2 , has no division-by-zero problem at x = 0, it is not, strictly-speaking, "equal" to the original expression.

To make the simplified form truly equal to the original form, I have to explicitly state this "x cannot be zero" exclusion. Warning: Your particular textbook or instructor might not make this distinction. If you're not sure if your teacher cares about this technicality, please make sure to ask before the next test.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
