That 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 x. In mathematics the logarithm is the inverse function to exponentiation. 1 If a 1 and x y then l o g a x l o g a y.
Its precise definition is as follows.
Try this example now. Logarithmic inequalities are inequalities in which one or both sides contain a logarithm. The equation Lnx8 can be rewritten Step 2. Last post we talked about radical inequalities.
