Know that A and B are reciprocal, C and D are reciprocal, and the absolute value of X =5.

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.
