I would first do 1.05 log x = log 9
I will guess that you are using the common (base-ten) log, but I'm afraid I don't follow your steps...?
To learn the properties of logs, try here
. But I think your only error is that you changed the "9" to a "1.09", or vice versa.
Then next step in solving the log equation
is to isolate the x-term, and then convert back to exponentials:. . . . .. . . . .
Simplify the left-hand side to just "x", and use your calculator if you need a decimal approximation for the right-hand side.

There may be two square roots, but unfortunately you haven't used grouping symbols to say where they go. Do you mean either of the following?. . . . .
ln(sqrt(x)) + sqrt(x) = 3. . . . .
ln(sqrt(x) + sqrt(x)) = 3
When you reply, please provide the instructions for this equation, along with a clear listing of everything you have tried so far. Thank you!
