The correct Answer is:
To solve the equation \( |x| + |-x| = \frac{\log_3(x-2)}{|\log_3(x-2)|} \), we will break it down step by step. ### Step 1: Simplify the Left-Hand Side The left-hand side of the equation is \( |x| + |-x| \). We know that: \[ |-x| = |x| \] Thus, we can simplify: \[ |x| + |-x| = |x| + |x| = 2|x| \] So, the equation becomes: \[ 2|x| = \frac{\log_3(x-2)}{|\log_3(x-2)|} \] ### Step 2: Analyze the Right-Hand Side The right-hand side \( \frac{\log_3(x-2)}{|\log_3(x-2)|} \) can take two values: - It is \( 1 \) when \( \log_3(x-2) > 0 \) (i.e., \( x - 2 > 1 \) or \( x > 3 \)) - It is \( -1 \) when \( \log_3(x-2) < 0 \) (i.e., \( x - 2 < 1 \) or \( x < 3 \)) ### Step 3: Set Up Cases We will consider two cases based on the value of the right-hand side. #### Case 1: \( \log_3(x-2) > 0 \) In this case, we have: \[ 2|x| = 1 \] This implies: \[ |x| = \frac{1}{2} \] Thus, \( x = \frac{1}{2} \) or \( x = -\frac{1}{2} \). However, for \( x > 3 \), neither of these values is valid. #### Case 2: \( \log_3(x-2) < 0 \) In this case, we have: \[ 2|x| = -1 \] This is impossible since \( |x| \) cannot be negative. ### Step 4: Determine Valid Interval From the analysis, we need to ensure that \( x - 2 < 1 \) for the logarithm to be negative, which gives us: \[ x < 3 \] Also, \( x - 2 > 0 \) implies: \[ x > 2 \] Thus, we have the interval: \[ 2 < x < 3 \] ### Step 5: Find \( a + b \) Here, \( a = 2 \) and \( b = 3 \). Therefore: \[ a + b = 2 + 3 = 5 \] ### Final Answer The value of \( a + b \) is \( \boxed{5} \).

To solve the equation \( |x| + |-x| = \frac{\log_3(x-2)}{|\log_3(x-2)|} \), we will break it down step by step. ### Step 1: Simplify the Left-Hand Side The left-hand side of the equation is \( |x| + |-x| \). We know that: \[ |-x| = |x| \] Thus, we can simplify: ...
