Logarithm of 1 Property
The Logarithm of Property states that the logarithm of to any valid base is always equal to . If and , then . This fundamental algebraic property serves as a core simplification rule and corresponds to the exponential fact that any non-zero base raised to the power of equals . For the natural logarithm, this property is expressed as .
