Math Problem Statement

حل

|x - 1| = 0, ∀x∈(0,1)

Solution

The problem presented involves the equation:

x1=0,x(0,1)|x - 1| = 0, \quad \forall x \in (0, 1)

Let's break this down:

  1. Absolute Value Property: The absolute value equation x1=0|x - 1| = 0 implies that the expression inside the absolute value must be zero. That is: x1=0    x=1x - 1 = 0 \implies x = 1
  2. Domain Restriction: The condition x(0,1)\forall x \in (0, 1) means that xx is restricted to values between 0 and 1, excluding 1.

Analysis:

  • The equation x1=0|x - 1| = 0 is only true when x=1x = 1.
  • However, x=1x = 1 is not in the interval (0,1)(0, 1), as the interval is open and excludes the endpoint 1.

Therefore, the equation x1=0|x - 1| = 0 cannot be true for any xx in (0,1)(0, 1), making the statement false.

Conclusion:

The correct choice is "False."


Would you like any further explanation or details? Here are some related questions to deepen understanding:

  1. What is the definition of an open interval in set theory?
  2. How would the answer change if the interval were closed, [0,1][0, 1]?
  3. What are the general properties of absolute value equations?
  4. How does the equation x1=0|x - 1| = 0 behave over different intervals?
  5. Can we find any other intervals where x1=0|x - 1| = 0 holds?

Tip: Remember, absolute value equations are useful for finding distances from a reference point!
