(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I have 2 problems ,which are:

1) Solve :log_{7 }(x^{3}+27) + log_{7}(x+3)

2) Solve for x:log_{5}( 5^{1/x}+ 125) log_{5 }6+1+1/2x

2. Relevant equations

3. The attempt at a solution

The first one tried like this :

log_{7}{ (x^{3}+27)/(x+3) }= 2

or 7^{2}= (x^{3}+27)/(x+3)

But I don't know how to proceed beyond it please help!

in second one

log_{5}{( 5^{1/x}+ 125) /6}=1+1/2x

but I can't proceed here too.

I need an urgent help!

Thank You!
