WebA logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are the inverse (opposite) of exponentiation. Historically, they were useful in multiplying or dividing large numbers. An example of a logarithm is = . In this logarithm, the base is 2, the argument is 8 and the answer is 3. WebLogarithm quotient rule. The logarithm of a division of x and y is the difference of logarithm of x and logarithm of y. log b ( x / y) = log b ( x) - log b ( y) For example: log b …
WebSet each factor equal to zero then solve for x x. x x as potential solutions. Make sure that you check the potential answers from the original logarithmic equation. You should agree that \color {blue}x=-32 x = −32 is the only solution. That makes \color {red}x=4 x = 4 an extraneous solution, so disregard it.
WebWhat is logarithm equation? A logarithmic equation is an equation that involves the logarithm of an expression containing a varaible. What are the 3 types of logarithms?
