The absolute value of the difference between a number and 3 is the opposite of the number,

The absolute value of the difference between a number and 3 is the opposite of the number,

Let this number be X
︱x-3︳=-x
The solution is x = 3 / 2

If the absolute value of x-3 and the absolute value of Y + 1 / 2 are opposite to each other, then x =? Y =?

Second, if the absolute value of x-3 and (y-4) ^ 2 are opposite numbers, then: | x-3 | + | y-4) ^ 2 | = 0 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; x-3 = 0 & nbsp;, x = 3 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp

If M and N are opposite to each other, P and Q are reciprocal to each other, and the absolute value of a is equal to 2, find the value of M + N divided by the square of 2010a - 2010pq + quarter a

1

Given that a and B are opposite numbers, M is a number whose absolute value is equal to one, find the value of (a + b)
Is to find the square of (a + b) + the square of M

A. B is reciprocal, a + B = 0, the square of 0, M is equal to 1, and the square of M is equal to 1
So the result is 1

Given that A.B is the opposite number, C.D is the reciprocal, the absolute value of M is 3, find m + cd-a + B
----
Square of M

∵ A.B is the opposite, C.D is the reciprocal, and the absolute value of M is 3,
∴ a＋b＝0,c·d＝1,m＝±3,m²＝9
∴ ﹙m＋cd＋a＋b﹚/m²
＝﹙m＋1＋0﹚/9
＝﹙m＋1﹚/9.
① When m = 3, the original formula is 4 / 9;
② When m = - 3, the original formula is - 2 / 9
