Log z = ln (r) + i (θ+2nπ) = ln (√ (x2 + y2)) + i arctan (y/x)) Logarithm problems and answers Problem #1 Find x for log 2 (x) + log 2 (x -3) = 2 Solution: Using the product rule: log 2 (x∙ (x -3)) = 2 Changing the logarithm form according to the logarithm definition: x∙ (x -3) = 2 2 Or x2 -3 x -4 = 0 Solving the quadratic equation:
In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number?
This free log calculator solves for the unknown portions of a logarithmic expression using base e, 2, 10, or any other desired base.
Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = log b n. For example, 2 3 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log 2 8.
An exponential equation is converted into a logarithmic equation and vice versa using b x = a ⇔ log b a = x. A common log is a logarithm with base 10, i.e., log 10 = log.
A log isn’t the opposite of an exponent, it is just a different way of writing an exponent. However, you could say that the operations of raising a number to an exponent and taking the log of that expression are inverse operations.
