**MathMate**, Wednesday, August 26, 2009 at 2:52pmUsing the relation

ln(e^{x}= x

For

e^{5x}= 2

Take natural log on both sides,

ln(e^{5x}) = ln(2)

5x = ln(2)

x = ln(2) / 5

Now make your pick for the answer.

**bobpursley**, Wednesday, August 26, 2009 at 2:55pmtake the ln of both sides

5x=ln2

x= 1/5 ln2

so, none of the choices are correct, unless on answer b you meant 1/5 ln2
