Bfe4 - 7x 9 Show Step 2 Now we can take the logarithm of both sides and because we have a base of bfe in this problem the natural logarithm is probably the best choice. So putting this into exponential form we end up with x² plus 10x plus 25 is equal to 3 to the 4th. Recall since loga logb is equivalent to a b we may apply logarithms with the same base on both sides of an exponential equation.
Tricks to Help with Solving Log Equations.
In these cases we solve by taking the logarithm of each side. As with exponential equations we can use the one-to-one property to solve logarithmic equations. Understand the how and why See how to tackle your equations and why to use a particular method to solve it making it easier for you to learn.
