Answer:
The partial sum s Subscript n today would be [tex]S_{13 \ billon}= 39.2523[/tex]
Step-by-step explanation:
From the question we are told that
n = 13 billion years
The partial sum is given as
[tex]S_{n} = 1+ ln(n) * ln(10)[/tex]
Converting n to seconds
[tex]n = (13 * 10^9) * (365 days / year) *(24 hr /day) * (3600/h) = 4.09968 *10^{16}[/tex]
The
[tex]S_{13billion} = 1 + ln(4.0*10^{16}) ln(10)[/tex]
[tex]S_{13 \ billon}= 39.2523[/tex]
