logₐ(m × n) = logₐ(m) + logₐ(n)
logₐ(m ÷ n) = logₐ(m) - logₐ(n)
logₐ(mⁿ) = n × logₐ(m)
logₐ(b) = logₓ(b) ÷ logₓ(a)

Logarithms are the inverse operations of exponentiation. In simpler terms, if we have an exponential equation like 10³ = 1000, the logarithm asks: "10 raised to what power equals 1000?" The answer is 3, so we write log₁₀(1000) = 3.
Our calculator supports several types of logarithmic calculations:
