However, the left side can be re-written, using the properties of exponentials, as eax−bx = e(a−b)x, so we have that e(a−b)x = C. Now, taking the natural logarithm of both sides, we have that (a−b)x = lnC. Dividing both sides by a−b gives the expression for x: x = lnC a−b. 8. melbourne beach wedding venues
