Heir counterparts in the private sector. The eight papers and accompanying discussions in this volume of proceedings are about "compliance sampling" to determine how well environmental standards are met. These papers provide valuable guidance in the planning of future environmental studies. The papers address many aspects of compliance, and are intended for statisticians involved in planning how to ascertain general levels of compliance and identify noncompliers for special attention.
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.
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. 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. If all three terms are valid, then the equation is valid. Simplify the left side of the above equation: By the properties of logarithms, we know that Step 3: The equation can now be written Step 4: Let each side of the above equation be the exponent of the base e: Simplify the above equation: In the case of this problem, then Step 6: Factor the left side of the above equation: If the product of two factors equals zero, at least one of the factor has to be zero.
Why is 9 the only solution? We defined our domain to be all the real numbers greater than 3. You can check your answer by graphing the function and determining whether the x-intercept is also equal to 9.
If it is, you have worked the problem correctly. You could also check your answer by substituting 9 for x in the left and right sides of the original equation.
If, after the substitution, the left side of the equation has the same value as the right side of the equation, you have worked the problem correctly. If you would like to review another example, click on Example. Work the following problems.

The determination of a fission-track age (a number that relates to the observable track density) depends on the same general equation as any radioactive decay scheme: it requires an estimate of the relative abundance of the parent isotope and of the daughter product.
Question Rewrite as a logarithmic equation e^y=3 Answer by ewatrrr() (Show Source): You can put this solution on YOUR website! Hi e^y=3. 1.
To solve a logarithmic equation, rewrite the equation in exponential form and solve for the variable. Step 2: 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.
