Calculate Log Base 5 of 21
To solve the equation log 5 (21) = x carry out the following steps.- Apply the change of base rule: log a (x) = log b (x) / log b (a) With b = 10: log a (x) = log(x) / log(a)
- Substitute the variables: With x = 21, a = 5: log 5 (21) = log(21) / log(5)
- Evaluate the term: log(21) / log(5) = 1.39794000867204 / 1.92427928606188 = 1.8916681496082 = Logarithm of 21 with base 5
Additional Information
- From the definition of logarithm b y = x ⇔ y = log b(x) follows that 5 1.8916681496082 = 21
- 5 1.8916681496082 = 21 is the exponential form of log5 (21)
- 5 is the logarithm base of log5 (21)
- 21 is the argument of log5 (21)
- 1.8916681496082 is the exponent or power of 5 1.8916681496082 = 21
