Question

log(x)+log(x+2)=2

Answer 1

log(a)+log(b)=log(ab)

Answer 2

is there any way you can help me solve the problem?

Answer 3

Yep.
I just gave you a hint.
Use that hint on the left hand side.

Answer 4

so I tried using that formula but the answer is a huge number.

Answer 5

So you did log(x(x+2))=2 because that is what I asked you to do.

Answer 6

Then base 10 on both sides so you can undo that log on that one side.

Answer 7

\[10^{\log(x(x+2))}=10^2 \]

Answer 8

yes i did that and from there I get X^2+2x=10^2 which becomes x^2+2x-100?

Answer 9

Solve for x and see if both solutions will work.
