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.

1. Here, we show you a step-by-step solved example of logarithmic equations. This solution was automatically generated by our smart calculator: $\log_4\left (x\right)=3$. 2. Express the numbers in the equation as logarithms of base $4$. $\log_ {4}\left (x\right)=\log_ {4}\left (4^ {3}\right)$. 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.
log 2 [ (x) (x − 2)] = 3. log 2 (x2 − 2 x) = 3. Now the equation is arranged in a useful way. At this point, I can use The Relationship to convert the log form of the equation to the corresponding exponential form, and then I can solve the result: log 2 (x2 − 2 x) = 3. 2 3 = x2 − 2 x. 8 = x2 − 2 x. 0 = x2 − 2 x − 8.
