for example
3 log (base5) 2 - (1/2)log (base5) 9

how would someone come to work this out
i know that you are suppose to divide the 2nd part by the 1st
but im not sure where does the coefficients come in
would that mean you multpily the coefficients

rewrite the second one so that it is - log (base5) 3
taking the square root of 9
do the same for 2^3 so that it is now 8
log (B5) 8 - log (B5) 3
