Hi,
Usually for question like 1/(e^x) I can get rid of the fraction by writing it as e^-x. FOr a question like (e^x+1)/e^x how do I do this? It simplifies down to e^-x+1 but I don't get how to do it.
thanks

Because

$$\frac{a+b}{c} = \frac{a}{c} + \frac{b}{c}$$

You have a typo...And besides,the idea was to make him solve the exercise,not doing it for him... :grumpy:

A direct answer to your exact question is (e^x + 1)*e^-x, just like your 1/e^x example. Don't forget the distributive property of multiplication over addition.
