Consider the fact that (8^k)/k! are positive for all k. Thus they cannot sum to 0.karush said:$\tiny{206.b.46}$
\begin{align*}
\displaystyle
S_{book}&=\sum_{k=1}^{\infty}
\frac{8^k}{k! }=0\\
S_{TI}&=\sum_{k=1}^{\infty}
\frac{8^k}{k! }=e^8-1\\

$\textsf{ 2 different answers?}$
Summing 2 different answers means to add together the numerical values of two distinct answers, resulting in a single combined value.
Yes, you can sum two answers from different categories or fields as long as they both have numerical values. For example, you can sum the answers from a math problem and a physics problem.
No, there is no specific formula for summing 2 different answers. It simply involves adding the numerical values together using basic addition principles.
Yes, you can sum more than 2 different answers by following the same principles of addition and adding all the numerical values together.
Summing 2 different answers can be useful in various scientific experiments or calculations where multiple values need to be combined to find a final result. It can also be used to check the accuracy of calculations by comparing the summed value to an expected result.
