SOLUTION: solve for x: e^x - 8e^-x = 2 Ive tried to get these all in terms of base 2, but do not know what to do from there. So i had (2^0)(e^x)-(2^3)(e^-x)=2^1

You can put this solution on YOUR website!
solve for x:
e^x - 8e^-x = 2
Multiply by e^x
e%5E%282x%29+-+8+=+2e%5Ex
e%5E%282x%29+-+2e%5Ex+-+8+=+0
%28e%5Ex+-+4%29%2A%28e%5Ex+%2B+2%29+=+0
e%5Ex+=+4
x = ln(4)
