If 1 / a > 1, then a

If 1 / a > 1, then a


2,
The original proposition and the inverse proposition are true,
No proposition and inverse proposition are false



If x ^ 2-3x + 2 = 0, then the inverse proposition of x = 1 or x = 2 and its true or false


If x = 1 or x = 2, then x ^ 2-3x + 2 = 0
True proposition



If xy = 0, then the inverse proposition of x = 0 and y = 0 is?


Converse negative proposition:
If x ≠ 0 or Y ≠ 0, then XY ≠ 0



If xy = 0, then at least one of X and Y is 0-----


If XY ≠ 0, then none of X and Y is 0



Is the inverse proposition true and false?


Converse proposition and negative proposition are converse proposition, so they are true and false



Absolute opposite number
--|-8 | =? -- | 97 | =? -- | - 2 |? 7 is the opposite number of? - | - 8 |?
I preview in advance. I'm very generous


--|-8 | = -- 8 -- | - 97 | = -- 97 -- | - 2 | = -- 27 is the opposite of -- 7 -- | - 8 |
By definition:
The absolute value of a positive number is itself, the absolute value of a negative number is its opposite, and the absolute value of 0 is 0
On the contrary, the number is to replace the sign that is a number with the opposite (this is the dead method)
Make a suggestion: the above topic is the topic of junior high school, I suggest you buy some counseling books, because junior high school mathematics is a little difficult, about counseling books, you can buy: dial or multiple learning method and so on



The value of 1, 2013 is. 2, and the position of the absolute value of any rational number on the number axis is. 3, if a = - A,
The value of 1, 2013 is
2. The position of the absolute value of any rational number on the number axis is
3. If a = - A, then the corresponding point of real number a on the number axis must be at
4. If there is a point on the number axis to the left of the origin and the distance to the origin is 2 / 3, then the number represented by this point is


2013 is at the origin or on the right



Given that the vectors a, B and C satisfy the absolute value a = absolute value b = 2, the absolute value C is equal to 1, (A-C) * (B-C) = 0, then the value range of the absolute value (a-b) is?


(a-c)(b-c)=0---->ab-c(a+b)+c^2=0---->(ab+1)^2=[c(a+b)]^2,
(ab)^2+2(ab)+1



A times B is not equal to 0, C is the smallest natural number, find the absolute value of a divided by a + B divided by B + 2008 multiplied by C
Write all the methods, preferably with examples


Suppose 0 is the minimum natural number: when a and B are both positive, value = 2; when a and B are both negative, value = - 2; when a and B are both positive and negative, value = 0; suppose 1 is the minimum natural number: when a and B are both positive, value = 2010; when a and B are both negative, value = 2006; when a and B are both positive and negative, value = 2008



The product of three continuous natural numbers is equal to 120, how to calculate the natural number in the middle is 5


Let the middle be x, then the three numbers are X-1, x, x + 1
Then (x-1) * x * (x + 1) = 120
The solution is x = 5
