Log-log graphs scale both axes logarithmically, which causes functions of the form f(x) = a · xk to be depicted as straight lines with slope equal to the exponent k.

In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number?

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 …

Sep 26, 2025 · 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, …

The log calculator (logarithm) calculates the value of a logarithm with an arbitrary base.

The logarithmic equation is one that uses logarithms, the unknown variable in the equation is included in the argument of the logarithm (the expression within the log).
