Q. Find the value of x x that solves the equation ln(x3)ln3=0 \ln (x-3)-\ln 3=0 .\newlineAnswer:
  1. Combine logarithms: To solve the equation ln(x3)ln3=0\ln(x-3) - \ln 3 = 0, we can use the property of logarithms that allows us to combine the two logarithms into one by division since subtraction of logarithms corresponds to division of their arguments.\newlineSo, we rewrite the equation as ln(x33)=0\ln\left(\frac{x-3}{3}\right) = 0.
  2. Exponentiate both sides: Next, we can exponentiate both sides of the equation to remove the natural logarithm. The equation eln(x33)=e0e^{\ln(\frac{x-3}{3})} = e^0 will simplify because ee and ln\ln are inverse functions.\newlineThis gives us x33=e0\frac{x-3}{3} = e^0.
  3. Simplify the equation: Since e0e^0 is equal to 11, the equation simplifies to (x3)/3=1(x-3)/3 = 1.
  4. Isolate the term: To solve for xx, we multiply both sides of the equation by 33 to isolate the term (x3)(x-3). This gives us x3=3x-3 = 3.
  5. Solve for x: Finally, we add 33 to both sides of the equation to solve for xx. This gives us x=3+3x = 3 + 3, which simplifies to x=6x = 6.
