If logb2=m logb3=n logb5=p then what is the value of logb(2.4)
in terms of m, n, p?
-----
logb(4/10) = logb(4)-logb10) = 2*logb(2)-[logb(2)+logb(5)]
----
= 2m-[m+p]
---
= m-p

log%28b%2C%282.4%29%29 = log%28b%2C%2824%2F10%29%29 = log%28b%2C%2812%2F5%29%29 = log%28b%2C%282%5E2%2A3%29%29 - log%28b%2C%285%29%29 = 2%2Alog%28b%2C%282%29%29 + log%28b%2C%283%29%29 - log%28b%2C%285%29%29 = 2m + n - p.

Solved.
