e%5E%28x%2B4%29+=+6

In order to "undo" the "e" raised to the power, you must take the ln of each side of the equation. Remember that the ln%28e%5Ex%29=+x+:

ln%28e%5E%28x%2B4%29%29+=+ln%286%29+
x%2B4+=+ln%286%29+

Finally subtract 4 from each side:
x=+ln%286%29+-+4
x= -2.208 approximately.

solve equation
e^(x+4)=6
ln%28e%29%5E%28x%2B4%29=ln%286%29 Take the natural log of both sides
%28x%2B4%29ln%28e%29=ln%286%29 Power Rule
x%2B4=ln%286%29 ln(e)=1
x%2B4-4=ln%286%29-4
x=ln%286%29-4
x=-2.208240531
Happy Calculating!!!
