Calculator Help

I can do some of the problems on this, but some I can't figure out. The answers on these listed I am getting wrong, I covered up the ones I know. I am obviously making a mistake typing them in my calculator. The ones with the e not in the exponent but the base, I can't figure out how to enter that. I use 2nd-LN for e^.

Any help? My calculator is a ti-30

I got it almost all figured out!

One last question, how do i get the "e" in the exponent like that? I don't think it's 2nd->LN because that would put it at e^ again.

?

You need to use brackets:

$\displaystyle 10^{3e-5\sqrt2}$ is 10^(3e^1-5sqrt(2)).
