$${a}×{b}^x={c}$$
$$log({b}^x) = log(\frac{{c}}{{a}})$$
$$log({b}^x)= {=round( log({c}/{a}) , 3)}$$
$$x×log({b}) = {=round( log({c}/{a}) , 3)}$$
$$x×{=round( log({b}) ,3 )} = {=round( log({c}/{a}) , 3)}$$
$$x = \frac { {=round( log({c}/{a}) , 3)} } { {=round( log({b}) ,3 )} }$$
$$x = {=round( (round( log({c}/{a}) , 3)) / (round( log({b}) ,3 )) , 3) }$$
