## 3kgtlife 3 years ago Solve the logarithmic equation. log 4 x=log 3 + log(x+3)

1. asnaseer

use this log rule to first simplify the right-hand-side:\[\log(a)+\log(b)=\log(ab)\]

2. 3kgtlife

log(3)+log(4x)=log(x+3)??

3. asnaseer

where did you get that from?

4. asnaseer

use the rule I gave to first simplify this:\[\log 3 + \log(x+3)\]

okk

7. ksaimouli

use as she says

8. ksaimouli

log 4x/3

9. 3kgtlife

what do I do after that?

10. ksaimouli
11. ksaimouli

first learn rules

12. asnaseer

what do you get after using the rule for this expression?\[\log 3 + \log(x+3)\]

13. asnaseer

@3kgtlife do you understand?

14. 3kgtlife

Im trying hold up

15. 3kgtlife

I am lost

16. asnaseer

do you know the various rules for logs?

17. 3kgtlife

no

18. asnaseer

Then I suggest you first learn about them (using the link posted by ksaimouli above) and then come back to do this problem.

19. 3kgtlife

alright thanks

20. asnaseer

yw :)

use log rules: log(a) + log(b) = log(a*b) 10^log(a)=a
