Best ResponseYou've already chosen the best response.0is this log base 3 or log base ten?

Best ResponseYou've already chosen the best response.0so it is \[log_3(x1)+log_3(x+25)=3\]?

Best ResponseYou've already chosen the best response.0if so then combine in to one logarithm using the property of logs: \[log(A)+log(B) = log(AB)\] \[log_3(x1)(x+25)=3\]

Best ResponseYou've already chosen the best response.0then write in equivalent exponential form to get \[(x1)(x+25)=3^3=27\] \[x^2+24x25=27\] \[x^2+24x52=0\] \[(x2)(x+26)=0\] \[x=2\] \[x=26\] but 26 not a solution because you cannot take the log of a negative number, so answer should be 2
