It is known that a and B are opposite to each other, m and N are reciprocal to each other, and the square of X is equal to nine,
Then a + B = 0
mn=1
x=±3
The third power of X - (a + B + Mn) the 2013 power of X + (a + b) + (- Mn) the 2013 power
=The third power of (± 3) - (0 + 1) (± 3) + the 2013 power of 0 + (- 1)
=±27-（±3）+0-1
=±24-1
=23 or - 25

If a, B are reciprocal and m, n are opposite, then the square of 2 (M + n) + 3AB is equal to?

A. B is reciprocal, ab = 1
M. N is opposite to each other, M + n = 0
2(M+N)²+3AB
=2*0²+3*1
=0+3
=3

a. B is the reciprocal, m, n is the opposite. So - (5m + 5n-3ab / 2) ^ is equal to

a. B is reciprocal = a * b = 1
m. N is the opposite number = m + n = 0
-（5m+5n-3ab/2)^2=-（0-3/2）^2=-4/9
