In mathematics, the logarithm is the inverse function to exponentiation.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 the simplest case, the logarithm counts the number of occurrences of the same factor in repeated multiplication; e.g., since 1000 = 10 × 10 × 10 = 10 3, the "logarithm base

Convert log 3 (6) to an expression with logs having a base of 5. I can't think of any particular reason why a base- 5 log might be useful, so I think the only point of these problems is to give you practice using change-of-base.

Solve the inequality log0.3 |4 - 3x| < 0.

Changing the logarithm form according to the logarithm definition: x∙(x-3) = 2 2. Or. x 2-3x-4 = 0. Solving the quadratic equation: x 1,2 = [3±√(9+16) ] / 2 = [3±5] / 2 = 4,-1. Since the logarithm is not defined for negative numbers, the answer is: x = 4. Problem #2. Find x for. log 3 (x+2) - log 3 (x) = 2.

Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history

If you want to compute a logarithm with an arbitrary base, but can access only a For example, 2 3 = 8 ⇒ log 2 8 = 3 (the logarithm of 8 to base 2 is equal to 3, because 2 3 = 8). Similarly, log 2 64 = 6, because 2 6 = 64. Therefore, it is obvious that logarithm operation is an inverse one to exponentiation. This free log calculator solves for the unknown portions of a logarithmic expression using base e, 2, 10, or any other desired base. Learn more about log rules, or explore hundreds of other calculators addressing topics such as math, finance, health, and fitness, among others. Log 0.3 can be written as log (3/10) and as we know log (a/b) = log (a) - log(b).

Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history Vinegar typically has a pH of about 3. The difference of 4 corresponds to a ratio of 10 4 of the activity, that is, vinegar's hydronium ion activity is about 10 −3 mol·L −1. Semilog (log–linear) graphs use the logarithmic scale concept for visualization: one axis, typically the vertical one, is scaled logarithmically.

If Log a b = x, then a x =b.
