Find: X+(A+B +(-CD) squared X+(A+B) 2004 power sum (-CD) 2005 power) = =
According to the meaning of the question, A+B=0, CD= 1, and X = 5.
( 1)x=+5
The original formula = 25+(0+1) * 5+0+(-1) 2005 = 25+5-1= 29.
(2)x=-5
The original formula = 25+(0+1) (-5)+(-1) 2005 = 25-5-1=19 upstairs, and x is +-5.
You got +5 points.
