If AB is opposite to each other and CD is reciprocal to each other, the absolute value of M is 1, and the value of (a + b) cd-2014m is obtained

If AB is opposite to each other and CD is reciprocal to each other, the absolute value of M is 1, and the value of (a + b) cd-2014m is obtained

±2014

Given that two unequal numbers a and B are opposite to each other, C and D are reciprocal | x | = 1, find - 2008 (a + b) - (- CD) 2009 cube + X

The estimate is - 2008 (a + b) - (- CD) ^ (2009 + x)
a+b=0
cd=1
x=±1
2009 + x = 2009 ± 1 is even
-2008(a+b）-（-cd）^(2009+x)
=-2008*0-(-1)^(2009±1)
=0-1
=-1

If a and B are opposite numbers and C and D are negative reciprocal, then the cube of a + the cube of B - the cube of C and the cube of D =?

a. B is opposite to each other, C and D are negative reciprocal to each other,
Then a + B = 0, CD = - 1
Cube of a + cube of b-cube of C cube of D
=（a+b）（a²-ab+b²）-（cd）³
=0-（-1）
=1
