To get the value of "e" the base of the natural logarithm you calculate the value of the exponential e^x function for x=1, in other words
value of "e"=e^(1)=2.718281828

To get the square you can use (e(^1))^2, but that is clumsy.
You can use the rule about exponential functions (e^a)*e^b)=e^(a+b)
Thus (e^1)*(e^1)=e^(1+1)=e^2

To access the exponential function press [SHIFT][LN]
and the square of "e" is obtained by pressing
[SHIFT][LN] 2 [ENTER]
The result is 7.389056099.

To draw the function Y1= square of exponential of X, you enter in the Y=editor
Y1=[SHIFT][LN] [ ( ] 2* [X, Theta, T] [ )]. The [X,Theta, T] key is the one under [ALPHA].
