For any other combinations the base and logarithm, just supply the other two numbers as inputs and click on the on the "CALCULATE" button. Have in mind that the value of the base must be positive, not equal to \$1\$. Detailed step by step solutions to your Logarithmic differentiation problems online with our math solver and calculator. Here is the standard equation for log: logb(x) = y Where, 1. For example, the binary logarithm of 1 is 0, the binary logarithm of 2 is 1 and the binary logarithm of 4 is 2. The logarithm (log) operation in mathematics is the inverse to exponentiation, meaning that the log of a number is the exponent to which another fixed number called a "base" was raised to produce the number. In other words if you have a problem, say log base 2 of 4, the answer is 2 because 2^2=4. For example log232 = 5, since 25 = 32. Inverse log calculator shows the calculation for finding the antilogarithm in base \$2\$ of \$10\$. It is often used in computer science and information theory. Evaluate log base 2 of 16. 2. The base b real logarithm of x when x<=0 is undefined when x is negative or equal to zero: log b (x) is undefined when x ≤ 0. Next, the base of the log needs to be chosen. This is an example of a simple logarithm as it basically counts the number of multiplications of the same factor - in this case 2. Find the base 2 logarithm of value using this calculator. The formula for solving this problem is y = b 3, where b is the logarithmic base, and y is the result.
