This is very simple. Before starting it we should remember the value of e? Value of e is 2.72. Whicih proved in an other place.
Value of e
We know that e = 2.72 (approximately)
= 0.3678 (approximate)
Therefore approximate value of e is 0.3678.
Similarly you can find the value of e^2, e^3, e^3, e^4... so on. In all cases you have to quoted the answer to three decimal places.
You can also check and evaluate negative and fractional powers of "e" such as e^(1/2) = 1.649 and e^-2 = 0.135
By using scientific calculator you can find the values of e's power more easily and accurate. To do this you can look for a button marked e^x on your scientific calculator.
