Question

if log 2 = a and log 3=b find log 25/8​

Answer 1

Hey mate....

Let’s start by simplifying log (25/8), i assume 10 to be base of log:

log(25/8)=

log 25 - log 8=

log 5^2 - log 2^3 =

2 log 5 - 3 log 2 =

2 log (10/2) - 3 log 2 =

2 (log 10-log 2) - 3 log 2 =

2(1-log 2) - 3 log 2 =

2 - 2 log 2 - 3 log 2 =

2- 5 log 2 =

2- 5a (After putting the value log 2=a, as provided in the question)

Hope this helps u....
