Given that x.y is opposite to each other and a.b is reciprocal, then the value of the 2012 power (-ab) of (xy) is the value of the 2013 power.

Given that x.y is opposite to each other and a.b is reciprocal, then the value of the 2012 power (-ab) of (xy) is the value of the 2013 power.

AB opposite to each other, A + B =0
C, d are reciprocal, so that the absolute value of the optical disk=1
X is 1/2, so X =±1/2 y is not a divisor at y =0
2 Of (a + b) 012-2 Power (CD)2012 square 1/X + y2013 power value
=2*0^2012-2*1^2012+1/ X 0^2013
=0-2+1/X+0
=1/X-2
=0 Or -4

If a, b are mutually opposite numbers, c, d are reciprocal, and a=0, then (a+b)2011 power +(cd)2012 power -(a/b)2013 power Come on, tonight. If a, b are mutually opposite numbers, c, d are mutually reciprocal, and a=0, then (a+b)2011 power +(cd)2012 power -(a/b)2013 power Come on, tonight.

Turns out it's second, seventh grade. Last semester, rational.
