Answer 5

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 \(\bf log_760\implies \cfrac{log_{10}60}{log_{10}7}\)
