X y log a a log a MN x y log a MN Now substitute the values of x and y in the equation we get above. Plug in the answers back into the original equation and check to see the solution works. Since the base is common therefore add the exponents.

Use the change-of-base formula. Lnpq ln p ln q. In mathematics the logarithm is the inverse function to exponentiationThat means the logarithm of a given number x is the exponent to which another fixed number the base b must be raised to produce that number xIn the simplest case the logarithm counts the number of occurrences of the same factor in repeated multiplication.

Taking log with base a on both sides. Logb mn logb m logb n. Log b x y y log b x For example.
