Hello there, Im wondering if you could offer some help on this questoin, I have been attempting to work through it, however cannot see exactly what route I should be taking to try and solve it;(adsbygoogle = window.adsbygoogle || []).push({});

Without using a calculator or table, show that;

2 < log(3) 25 < 3(log to the base 3 of 25)

and hence find the ceiling oflog(3) 75

Also calculatelog(5) 75in terms oflog(3)5

Thankyou for any help you can provide.

Craig:)

Edit:

Sorry i forgot to mention, what i have done so far is;

Shown that3^3 = 27and3^2 = 9, this is simply settinglog(3)x = 3 and 2and i get a values in which 25 lies in

9 < 25 < 27
