Properties 3 and 4 leads to a nice relationship between the logarithm and exponential function. This is a nice fact to remember on occasion. We will be looking at this property in detail in a couple of sections.
To solve a logarithmic equation, rewrite the equation in exponential form and solve for the variable. Solve for x in the equation Answer: As we know by now, we can only take the logarithm of a positive number.
Therefore, we need to make a restriction on the domain values of x so that the problem will be valid have an answer.
Simplify the left side of the original equation using Logarithmic Rule 1: We now have an equation of the form which implies that the expression a must equal the expression b or: You could also raise the base 2 to an exponent equal to the left side of the equation in Step 2, and you could raise the base 2 to an exponent equal to right side of the equation in Step 2: When the base is the same as the base of the logarithm, the above equation can be simplified to Step 5: Simplify the left side of the above equation: Subtract x and subtract 6 from both sides of the above equation: Use the quadratic formula to solve for x: There are two exact answer: However only one of the answers is valid.
Therefore, the exact and approximate answers are: Let's substitute the value in the original equation and determine whether the left side of the equation equals the right side of the equation after the substitution.
