Question

Which of the following shows the true solution to the logarithmic equation solved below? HURRY!

Answer 1

the second one is the answer on edg.

Answer 2

The correct option is: x = 1

Step-by-step explanation:
Although there are two solutions to the equation are given: -8 and +1, the true solution will be the one that satisfies the given equation. If we put "-8" into the equation
`log_2(x) + log_2(x+7) = 3`, the equation will not satisfy as the log of the negative number does not exist. If we put "+1" in the above equation, we would get "3" as an answer, meaning the true solution exists.

Hence the correct option is "x=1"
