Log base pi (41) what is the answer

$${{\mathtt{\pi}}}^{{\mathtt{x}}} = {\mathtt{41}} \Rightarrow {\mathtt{x}} = {\frac{{ln}{\left({\mathtt{41}}\right)}}{{ln}{\left({\mathtt{\pi}}\right)}}} \Rightarrow {\mathtt{x}} = {\mathtt{3.244\: \!059\: \!679\: \!588\: \!781\: \!6}}$$

yes, it works too :)

log_π(41)

Use the change of base formula:  =  log(41) / log(π)   ...   and use a calculator   ...

$${{\mathtt{\pi}}}^{{\mathtt{x}}} = {\mathtt{41}}$$

Put in calculator and solve.
