sorry I was a bit caught up  $\bf \textit{log change of base }\quad log_ab=\cfrac{log_cb}{log_ca}$

the "c" value could be anything, it just have to be the same top and bottom, so of course the common ones will be log base 10 $\bf log_{10}\ or \ ln$  or natural logarithm, thus $\bf log_760\implies \cfrac{log_{10}60}{log_{10}7}$
