对数是数学代数中重要的组成部分，对数是对求幂的逆运算，对数的一般形式为x=logₐN（a>0，且a≠1），其中a叫做对数的底数，N叫做真数。 使用对数计算器，我们只需输入对数的底数和真数，即可快速计算出对数，节约人工运算时间，提升对数的运算效率，为 ...

Free logarithm calculator - step-by-step solutions to help simplify logarithmic expressions.

如果 a x = N （a>0，且 a≠1），那么数 x 叫做以 a 为底的 N 的对数（Logarithm）， 记作 x = log a N 。 其中，a 叫做对数的底数，N 叫做真数。 底数：输入对数计算的底数，底数要求 >=0 且 ≠ 1 。底数输入 e ，表示计算自然对数。

This free log calculator solves for the unknown portions of a logarithmic expression using base e, 2, 10, or any other desired base.

Find the point at x = 2 x = 2. Tap for more steps... The log function can be graphed using the vertical asymptote at x = 0 x = 0 and the points (5,1),(1,0.30102999),(2,0.60205999) (5, 1), (1, 0.30102999), (2, 0.60205999).

The log base 2 calculator quickly computes the value of the logarithm function with base two, i.e., log₂(x) for arbitrary (positive) x.

2012年5月27日 · $$\log ^2 x$$ in place of $$(\log x)^2=\log x \times \log x$$ just in the same manner as we write $\sin^2 x = (\sin x)^2$ or any other "named" function's square. In general, you will see $(f(x))^n$ for the $n$th power of a function, and $f^n (x)$ in place of the $n$ times composition of $f$, i.e. $f^3(x)=f \circ f \circ f(x)$.
