怎么改::::
因为 │A+1│+(B-2)的平方=0
所以 A+1=0 B-2=0
所以 A=-1 B=2
所以(A+B)的2003次方+A的2004次方=2
1.Is that your dictionary in the lost and found case ?
2.How do you spell the pen?
3.Linda is her first name
4.That is your pencil
│A+1│+(B-2)的平方=0
所以得出|A+1|=0,A=-1
(B-2)=0,B=2
所以代进去
(A+B)的2003次方+A的2004次方
1的2003次方+(-1)的2004次方
=2
1不懂..
2How much do you spell a pen?
3Linda is her second name
4That is your pencil.
因为|A+1|+(B-2)的平方=0
所以A=-1;B=2,
(A+B)的2003次方+A的2004次方=2.
