(14x)^0 = 1

Steve these - signs are throwing me off....so even though that is - (14x)to the 0 - which = 1 it is a negative still?
Math Ms.Sue - Steve, Wednesday, January 9, 2013 at 2:54pm
yes. (14x)^0 = 1, so -(14x)^0 = -(1) = -1
now, (-14x)^0 = 1, because the - sign is part of what is raised to the 0 power.
Powers are done before +/- unless parens change the order.

ok...that helped - I get it...thank you

It's nice when it finally clicks, eh?
Maybe it will help if you consider a leading "-" as preceded by a 0. So,
-x^2 = 0-x^2
now it is clear that the powers get done before the subtraction.
-(-2x)^-3 = 0-(-2x)^-3 = 0 - 1/(-2x)^3 = 0 - 1/-8x^3 = 1/8x^3
