Dnml re write as a logarithmic equation

To solve a logarithmic equation, rewrite the equation in exponential form and solve for the variable. Let both sides be exponents of the base e.

By now you should know that when the base of the exponent and the base of the logarithm are the same, the left side can be written x. The equation can now be written Step 3: The exact answer is and the approximate answer is Check: You can check your answer in two ways.

Most Used Actions

You could graph the function Ln x -8 and see where it crosses the x-axis. If you are correct, the graph should cross the x-axis at the answer you derived algebraically. You can also check your answer by substituting the value of x in the initial equation and determine whether the left side equals the right side.

For example, if Ln 2, It does, and you are correct.

Natural Logarithms (to the base e)

Isolate the logarithmic term before you convert the logarithmic equation to an exponential equation. Divide both sides of the original equation by 7: Convert the logarithmic equation to an exponential equation: If no base is indicated, it means the base of the logarithm is Recall also that logarithms are exponents, so the exponent is.

The equation Step 3: Divide both sides of the above equation by 3: You can check your answer in two ways: If you choose graphing, the x-intercept should be the same as the answer you derived. If you choose substitution, the value of the left side of the original equation should equal the value of the right side of the equation after you have calculated the value of each side based on your answer for x.

Solve for x in the equation Solution: If we require that x be any real number greater than 3, all three terms will be valid.
