I have a $e^x$ button for taking exponentials (it's above the 'ln' button.)
On my calculator it's [shift]+[ln].

You should have an e^ button (and I'll be surprised if you don't) but if you don't then:

$$e^x \approx 2.71828459^x}$$

As well as other good approximations that you might be able to use a bit of your maths you've learnt to work out.
