Enter the logarithmic expression below which you want to simplify. The logarithm calculator simplifies the given logarithmic expression by using the laws of logarithms.
Write in Exponential Form log base 2 of 8=3. log2 (8) = 3 log 2 (8) = 3. For logarithmic equations, logb(x) = y log b (x) = y is equivalent to by = x b y = x such that x> 0 x> 0, b> 0 b> 0, and b ≠ 1 b ≠ 1. In this case, b = 2 b = 2, x = 8 x = 8, and y = 3 y = 3. b = 2 b = 2. x = 8 x = 8. y = 3 y = 3.

The formula of log to exponential form is \(log_aN = x\), is written in exponential form as \(a^x = N\). The logarithm of a number N to the base of a is equal to x, which if written in exponential form is equal to a to the exponent of x is equal to N.
log 2 (16) = 4. Logarithm as inverse function of exponential function. The logarithmic function, y = log b (x) is the inverse function of the exponential function, x = by. So if we calculate the exponential function of the logarithm of x (x>0), f (f -1 (x)) = blogb(x) = x.
Example: Calculate 1 / log 8 2. 1 / log8 2 = log2 8. And 2 × 2 × 2 = 8, so when 2 is used 3 times in a multiplication we get 8: 1 / log8 2 = log2 8 = 3. And we use the Natural Logarithm so often it is worth remembering this: loga x = ln x / ln a. Example: Calculate log 4 22.
