Beyond the Answer
To solve the equation \( \log (x+10) = \log x + \log 10 \), we can use the properties of logarithms. According to the product rule of logarithms, we can rewrite the right side: \[ \log (x+10) = \log (10x) \] Now, since the logarithmic functions are equal, we can set their arguments equal to each other: \[ x + 10 = 10x \] Next, we simplify this equation. Subtract \( x \) from both sides: \[ 10 = 10x - x \] \[ 10 = 9x \] Now, divide both sides by 9: \[ x = \frac{10}{9} \] Thus, the solution is: \[ x = \frac{10}{9} \approx 1.1111 \] So the final answer is: \( x = \frac{10}{9} \)
