# Thread: Natural Logs help

1. ## Natural Logs help

$ln (e^{x^2-y^2})$

Anyone able to help me?

$\log_ab^c = c\log_ab$

3. Use this formula:

$ln (a)^b=b \cdot ln(a)$

4. Another way to do basically what pickslides and Also sprach Zarathustra suggest is to use the fact that ln(x) and $e^x$ are inverse functions: $ln(e^x)= x$.
