Simplify the above equation: The equation can now be written Step 4: You can check your answer in two ways.
If we require that x be any real number greater than 3, all three terms will be valid. Let each side of the above equation be the exponent of the base e: Simplify the left side of the above equation: The exact answer is and the approximate answer is Check: The equation Step 3: You could graph the function Ln x -8 and see where it crosses the x-axis.
If all three terms are valid, then the equation is valid. Convert the logarithmic equation to an exponential equation: Let both sides be exponents of the base e. If you are correct, the graph should cross the x-axis at the answer you derived algebraically.
We defined our domain to be all the real numbers greater than 3. By the properties of logarithms, we know that Step 3: Solve for x in the equation. Divide both sides of the above equation by 3: You can check your answer by graphing the function and determining whether the x-intercept is also equal to 9.
If the product of two factors equals zero, at least one of the factor has to be zero. If no base is indicated, it means the base of the logarithm is You can check your answer in two ways: Work the following problems. Solve for x in the equation Solution:Answer to Express 4^5 = x as a logarithmic equation.
