Question

What is the first step in solving this logarithmic equation: log 3 + log (x + 1) = log (2x + 4)
A. x + 1 = 2x + 4
B. 3 + x + 1 = 2x + 4
C. log 3(x + 1) = log (2x + 4)
D. log (3 + x + 1) = log (2x + 4)

Answer 1

since there are two logs in the left side of the equation, and in order to be able to compare the left and right sides, you need to have one log on each side, so you need to combine the two logs on the left side by adding them according to the rule log a + log b = log ab

can you guess now which is the correct answer?
