How do you solve this?
i know you have to use the e^x identity but idk how to use it

Recall the exponential function's power series,

The given sum has instead of . We can adjust the given sum to get something usable. Notice that in the series expansion for , the degree of starts at 0, while in the given series, the degree starts at 1. We can actually rewrite the given series so that it starts at a different index:

Then this is exactly without the term. When , we have , so

the answer is 0.071

good luck! : d

step-by-step explanation:

if x = 2 you have to find x to finish the problem
