Re: exercise in logarithm

y* ln( x ) = ln( x^y ) , so
1/2 * ln( x ) = ln ( x^( 1/2 ) ) = ln( sqrt( x ) )

Put that into your exercise and you get:
ln (x/2) = ln( sqrt(x) )
x/2 = sqrt(x)
x^2 / 4 = x
x*x = 4*x
x = 4

Tell me if I'm wrong, but i think this is the correct answer.

It doesn't seem like he took over the computers of the hackers as well, though.
