Reasoning: Common logarithm is defined with base $10$.

$\log(x)=\log_{10}(x)$

Reasoning: Natural logarithm uses Euler's number as its base.

$\ln(x)=\log_e(x)$

Reasoning: The symbol $\ln$ denotes natural logarithm.

Reasoning: Common logarithm has base $10$.

$\log_{10}x$

Reasoning: Scientific calculators generally provide both:

$\log$

and

$\ln$

Reasoning: Since

$10^2=100$

therefore

$\log_{10}(100)=2$

Reasoning:

$\ln(x)=\log_e(x)$

Reasoning:

$e\approx2.71828$

Reasoning: Briggsian logarithm is another name for common logarithm.

Reasoning: Common and natural logarithms have different bases.

$10\ne e$

Reasoning:

$\ln(x)=\log_e(x)$

Reasoning: Natural logarithms are represented by the symbol $\ln$.

Reasoning: Common logarithm means logarithm with base $10$.

Reasoning:

$\log_{10}(10)=1$

while

$\ln(10)\approx2.303$

Therefore

$\ln(10)>\log_{10}(10)$

Reasoning: Exponential growth and decay formulas naturally involve the constant $e$.

Reasoning:

$\log$ uses base $10$

$\ln$ uses base $e$

Reasoning:

$\log_{10}(10)=1$

because

$10^1=10$

Reasoning: Natural logarithms are commonly used in growth, decay and continuous change models.

Reasoning:

$\ln(x)$ means logarithm to base $e$.

Reasoning:

$\log(x)=\log_{10}(x)$

and

$\ln(x)=\log_e(x)$
