Question

ln(x+2)+ln(x)=ln(35)

Answer 1

you want to solve for 'x' , right ?
use the property of log :
\(\log A+\log B =\log AB\)
on left side, so what you get for,
ln(x+2)+ln(x) =...?

Answer 2

ln(2x+2)?

Answer 3

Or x^2+2x?

Answer 4

x (x+2) = x*x + 2*x = x^2 +2x :)
so you get ln (x^2+2x) = ln 35
so now can you solve the quadratic equation
x^2+2x=35 ??

Answer 5

ln(x+2)+ln(x) =ln 35 ---> x^2+2x=35
because if ln A =ln B, then A=B

Answer 6

so ? could you calculate values of x ?
