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

You need to use parentheses.

Try the input: e^(5√2-2$\pi$).

When i hit the 2nd and x^2 giving me my square root sign it adds a parenthesis before the 2 and i can't get rid of it. I think that's messing it up.see

Manually add one more parentheses after 2 i.e e^(5√(2)-2$\pi$).

Thank you! I was hitting the negative key instead of the subtraction also.

How do the ones with the e in the exponent work? i can't find an e that does that?
 
It looks like you need a closing bracket at the very end of the expression.
 
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.

?

I have not used that calculator before but can't you simply remove the "^" symbol after you press 2nd->LN? If you can't, write it as e^1.

No, it won't let me just remove the ^ symbol sadly. here is the way you said to add the e on the bottom problem. The answer is coming out wrong.

im posting it in 2 pictures so you can see the whole problem i typed in.
