(Both because arg(0) is not defined and log( | 0 |) is not defined. Therefore, the equation log 3 (9) = 2 is equivalent to 3 = 9. Like exponential inequalities, they are useful in analyzing situations involving repeated multiplication, such as in the cases of interest and exponential decay. This problem is from a math contest held where I learn; I was unable to do much at all tinkering with it; I have observed the solution x = 1 x = 1 but haven't been able to prove there are no Algebra. In order to answer a question, what a logarithm is, let's take a look at the table below: In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number? Example: How many 2 s multiply together to make 8? Answer: 2 × 2 × 2 = 8, so we had to multiply 3 of the 2 s to get 8 So the logarithm is 3 How to Write it We write it like this: log2(8) = 3 So these two things are the same: Logarithm definition Logarithm rules Logarithm problems Complex logarithm Graph of log (x) Logarithm table Logarithm calculator Logarithm definition When b is raised to the power of y is equal x: b y = x Then the base b logarithm of x is equal to y: log b ( x) = y For example when: 2 4 = 16 Then log 2 (16) = 4 The product rule: log b ( M N) = log b ( M) + log b ( N) This property says that the logarithm of a product is the sum of the logs of its factors. Google Classroom. Limits. [latex]{\log _3}\left( {27{x^2}{y^5}} \right)[/latex] A product of factors is contained within the parenthesis.301.6. So we could say Log, base 3, of 81, is equal to-- I'll do this in a different colour. If x x and b b are positive real numbers and b ≠ 1 b ≠ 1, then logb(x) = y log b ( x) = y is equivalent to by = x b y = x.
