Find the solution of the exponential equation e^(2x+1)=36 in terms of logarithms, or correct to four decimal places.
e^(2x + 1) = 36 take the ln of both sides
ln e ^(2x + 1) = ln 36 and by a log property, we can write
(2x + 1) ln e = ln 36 but ln e just = 1 ... so we have....
2x + 1 = ln 36
2x = ln 36 - 1
x = [ ln 36 - 1 ] / 2 ≈ 1.2918 {rounded}
