how is this problem simplified to = 3

log, base 5, of 8 /log, base 5, of 2

???

2 to the power 3 is equal to 8. log laws

log_5(8) = log_5(2^3) = 3 x log_5(2)

I have another question : If log b< 0, then what can be said about b?

Is the (b) refering to base, or is this an understood base 10, of b

the problem is if this is understood as log_10 (b) I dont see anyway (b) can be < 0

10^(-1) = 0.1

So what is log_10 (0.1) ?

The usual convention is that if the base is not given it is base 10.

ahhh....... I see Log_10(.1) = -1

I managed to completely abolish log's of fractions from my thought process..........ðŸ˜€

thanks again
