a- 1=0,b+ 1=0
That is, a = 1 and b =- 1.
Then a2009+b2010 =12009+(-1) 2010 =1+0 = 2.
2. 1※2= 1^2 -2= 1- 1=- 1
(- 1)※3=(- 1)^2-3 = 1-3=-2
Therefore, (1※2) ※3=-2
3. According to the non-negative nature:
x- 1/2=0,y+5=0
That is, x = 1/2 and y =-5.
-2x^3-y^2
=-2*( 1/2)^3-(-5)^2
=- 1/4-25
=- 10 1/4
4. Meaning: ab= 1, c+d=0.
Because |x|=2
So x2 = (| x |) 2 = 2 2 = 4.
Original formula = (-AB) 2009-3 (C+D)+(X 2) 2.
=(- 1)^2009-3*0+4^2
=- 1+ 16= 15
