Answer:
log (48)/log (6)
Explanation:
Change of base formula is given a log, log (base a) of b, we can rewrite this as log b/log a with a base of whatever you choose, 10 is the best choice because you can then input this log into a calculator or make it easier to solve.
log (base 6) of 48 would then be log (48)/log (6)
I hope this helps :)
