You might also be interested in: I used different colors here to show where they go after rewriting in exponential form. We consider this as the second case wherein we have… We will transform the equation from the logarithmic to exponential form, and solve.

Convert the subtraction operation outside into a division operation inside the parenthesis.

You do it by isolating the squared variable on one side and the constant on the other. The second type looks like this… If you have a single logarithm on one side of the equation then you can express it as an exponential equation and solve.

Given Move the log expressions to the left side, and keep the constant to the right. Apply the Quotient Rule since they are the difference of logs. Given Move all the logarithmic expressions to the left of the equation, and the constant to the right.

Solve the logarithmic equation This problem is very similar to 7. Simplifying further, we should get these possible answers. Solve the logarithmic equation Collect all the logarithmic expressions on one side of the equation keep it on the left and move the constant to the right side.

Perform the Cross-Multiplication and then solve the resulting linear equation.

Therefore, exclude it as part of your solution. Solve the logarithmic equation Keep the log expression on the left, and move all the constants on the right side.

No big deal then. Make sure that you check the potential answers from the original logarithmic equation. The blue expression stays at its current location, but the red number becomes the exponent of the base of the logarithm which is 3.

Now set each factor to zero and solve for x. Solve the logarithmic equation This is an interesting problem. What we want is to have a single log expression on each side of the equation.

To get rid of the radical symbol on the left side, square both sides of the equation. Solving for x, you should get these values as potential solutions. The expression inside the parenthesis stays in its current location while the constant 3 becomes the exponent of the log base 3.

This is easily factorable. Study each case carefully before you start looking at the worked examples below. One way to solve it is to get its Cross Product.Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

Solving Logarithmic Equations.

Generally, there are two types of logarithmic equations. If you have a single logarithm on each side of the equation having the same base then you can set the arguments equal to each other and solve. The arguments here are the algebraic expressions represented by M and N.

Simplify: (x) (x-2) = x 2 −2x. • Use the change-of-base formula to rewrite and evaluate logarithmic expressions. Simplify. 7 Properties of Logarithms. 8 Properties of Logarithms. 9 Example 3 – Using Properties of Logarithms Write each logarithm in terms of ln 2 and ln 3.
