Re: ln(x) = ?
ln(x) means the "natural logarithm of x" and can also be represented as log[sub]e[/sub](x). The natural logarithm of a number x is the power to which e would have to be raised to equal x.
However, normally to find a solution to something you first need an equation (something with an equals sign), like ln(x) = 0 or ln(4x) = 2.
Perhaps in you could try looking here:

If all that makes sense scroll down to 'Natural Logarithms: Base "e"'
