The square of a + 3 and the absolute value of B-2 are opposite to each other

The square of a + 3 and the absolute value of B-2 are opposite to each other

The absolute value of B-2 and the square of a + 3 are both ≥ 0
So the sum of two nonnegative numbers is zero
Then both numbers are equal to 0
That is, the square of a + 3 = 0,
The absolute square value of B-2 = 0
So a = - 3, B = 2
I hope I can help you

If the absolute value of a + B-1 is opposite to the square of (a-b + 2), then a = () B = ()

The absolute value of a + B-1 > = 0, (the square of A-B + 2) > = 0
Opposite numbers
So:
a+b-1=0,a-b+2=0
a=-1/2,b=3/2

If the square of (√ 3-A) and the absolute value B-1 are opposite to each other, then the value of two parts of A-B is

（√3-a)^2+|b-1|=0
（√3-a)^2=0
|b-1|=0
√3-a=0
a=√3
b-1=0
B=1
2/(a-b)=2/(√3-1)=√3+1

The absolute value of A-2 is opposite to the square of (B + 1) kuaikkkkkkkkkkkkkkkkkkkkkkkk~

The absolute value of A-2 is opposite to the square of (B + 1)
|a-2|+(b+1)^2=0
a-2=0,b+1=0
a=2,b=-1

Let a, B be real numbers, and 1+a-（b-1） 1 − B = 0, calculate the value of a2005-b2006

From the meaning of the title, 1-B ≥ 0,
∴b≤1，
The original formula can be changed into
1+a+（1-b）
1−b=0，
According to the properties of nonnegative numbers, 1 + a = 0, 1-B = 0,
A = - 1, B = 1,
Therefore, a2005-b2006 = (- 1) 2005-12006 = - 1-1 = - 2

The real number a satisfies | 2006 − a|+ A − 2007 = a, then the value of a-20062 is () A. 2005 B. 2006 C. 2007 D. 2008

According to the meaning of the title, A-2007 ≥ 0,
The solution is: a ≥ 2007,
2006-a|+
a−2007=a，
A-2006+
a−2007=a，
Namely
a−2007=2006，
The square of both sides is: A-2007 = 20062,
A-20062 = 2007
Therefore, C is selected

The real number a satisfies | 2005 − a|+ If a − 2006 = a, then the value of the algebraic formula a-20052 is______ .

A kind of
A − 2006 makes sense,
∴a-2006≥0，
The original formula = a-2005+
A − 2006 = a, i.e
a−2006=2005，
∴a-2006=20052，
∴a-20052=2006．
So the answer is: 2006

Let AB be a real number, and the root sign 1 + a - (B-1) * radical 1-B = 0, find the 2006 square of a -- the 2007 power of B

The meaning of √ (1-B) is: 1-B ≥ 0,
The original equation is changed into:
√(1+a)+(1-b)√ (1-b)=0
If the sum of nonnegative numbers is 0, all items are 0,
∴1+a=0.
1-b=0
a=-1,b=1,
∴a^2006-b^2007
=1-1
=0.

If x- 3|= 7, then X=______ .

∵|x-
3|=
7，
∴x-
3=±
Seven
∴x=

7 or
