Question

Solve equation
log(2x + 1) = 1 + log (x-2)

Answer 1

The book said 21/8

Answer 2

so do you know any log properties?

Answer 3

\[\large \log a-\log b=?\]

Answer 4

a/b

Answer 5

you mean \[=\log[\frac{a}{b}]\] yes?

Answer 6

you may need to specify which base the log is in, natural log or base 10 ?

Answer 7

and yes we need to know what base is it!!!

Answer 8

yes, I used that

Answer 9

so are we dealing with natural log or base 10?

Answer 10

from the answer given, looks like base 10

Answer 11

right it has to be log base 10

Answer 12

we need to subtract log(x-2) from both sides to have two logs in one side
so we can use our property above! okay
can you do that

Answer 13

do it on the paper and show me what you got!!

Answer 14

(2x+1)/(x-2)=10

Answer 15

show all your work!

Answer 16

how did you get that?! it's right but show your work

Answer 17

oh well just finish solving that equation...

Answer 18

still
