How would I find for x in here

 

Please list all steps and explanations for I want to undersand as well.

 

\({3}^{x+2}={7}^{x-1}\)

\({18}^{x}=4^{2x+1}\)

\(ln(x^2-48)=ln(2x)\)

\(logx +log(x-21)=2\)

\({log}_{4}(x+1)+{log}_{4}5=2\)

\(3ln(2x)=6\)

\(ln(lnx)=0\)

 

Thank you!

We are not here to do all your homework for you.

Please post just one and try and answer others from the answer you are given.

 

These are all log questions.

 

Here are some  log rules.
