Question in comments, Please help..

OpenStudy (anonymous):

\[3^{x-2}=7\]

OpenStudy (anonymous):

im not sure if i should use log or ln, this is what i have \[x=\frac{ \ln7 }{ \ln3}+2\]

OpenStudy (anonymous):

i need to give an exact solution

OpenStudy (anonymous):

that looks right

OpenStudy (anonymous):

log or ln both are fine

OpenStudy (anonymous):

so could i substitute ln with log if i wanted to?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

OpenStudy (anonymous):

yes
