Question

log 9 - log x = 2 Can someone explain this? I got to log 9/x = 2 but I don't know what to do from there.

Answer 1

if you know this: \[\log _{a} b=c--> a ^{c}=b\].. then you can express your equation like: \[10^{2}=\frac{ 9 }{ x }\] because if the log have not basis is ten.. then clear x ;)

Answer 2

Oh thanks!
