series representation of ex with x = 1,write an infinite series representation for the number e. Answer in sigma form and also first 5 terms of the series. Write and compare both a decimal value of the approximation based on the first 5 terms of the series and a decimal approximation for the number e as determined by a calculator.

I understand how to being the problem and compare
