1. Diketahui u=10n-7 - Universityku

Jika n =5 maka u=
Jika n =-5 maka u=

2. Diketahui U=n²+4n-3
Jika n =0 maka u=
Jika n=5 maka u =

bantu ☹️

1. Diketahui u=10n-7

Nomor – 1

$u = 10n - 7 \ n = 5 to &u& =& 10(5) - 7 \ &u& =& 50 - 7 \ &u& =& bf43 \ n = - 5 to&u& = &10( - 5) - 7 \ &u& =& - 50 - 7 \ &u & = & bf - 57$

$:$

Nomor – 2

$u = {n}^{2} + 4n - 3 \ n = 0 to&u& = & {0}^{2} + 4(0) - 3 \ &u& = &0 - 3 \ &u& = & bf - 3 \ n = 5 to&u& = & {5}^{2} + 4(5) - 3 \ &u& = &25 + 20 - 3 \ &u& = & bf42$
