Please help me solve this problem.
\[1/2-\log_{16} (x)=\log_{16} (x+3)\]
put all logs on one side then add them by using log a+ logb = logab then use log a with base b=C then a=b^C so this is how it goes 1/2 = log x + log (x+3) = log x(x+3) = log(x^2 +3x) so then x^2 + 3x = 16^1/2 = 4 so it becomes a quadratic formula x^2 + 3x -4=0 so if you factorise (x-1)(x+4) =0 answers are x=1 and X=-4
why is it log(x^2+3x)? What happened to base 16?
I didnt see the equation button but you must put the base 16 in since they are the same you can add or take away
So... I can solve it without base 16 because they are all under the same base?
Yes that is why I wrote 16^1/2 because base is 16
Oh.. okay. I understand now. thanks. :D
ok going to bed now
Goodnight!
good night
