Which logarithmic identity is true?
logb(x)=ln(x)ln(b)\log_b(x) = \frac{\ln(x)}{\ln(b)}logb(x)=ln(b)ln(x)
logb(x)=ln(x)−ln(b)\log_b(x) = \ln(x) - \ln(b)logb(x)=ln(x)−ln(b)
logb(x)=ln(x)⋅ln(b)\log_b(x) = \ln(x) \cdot \ln(b)logb(x)=ln(x)⋅ln(b)
logb(x)=ln(b)ln(x)\log_b(x) = \frac{\ln(b)}{\ln(x)}logb(x)=ln(x)ln(b)
