Solve the following logarithmic equation algebraically log3
Solve the following logarithmic equation algebraically. log_3 (x) + log_3(x - 1) = log_3 6 Select the correct choice below and, if necessary, fill in A. The solution is x = (Simplify your answer. Type an integer or a fraction B. The solution is not a real number.
Solution
log3x + log3(x-1)=log36
log3(x(x-1)) = log36
x2-x-6=0
(x-3)(x+2)=0
x=3,-2
log cant take negative numbers
therefore x=3
