Question

(0,25) n+1 =1 supra 16

Answer 1

1/4 ·n +1=1/16
1/4 n=1/16 - 1
1/4 n=-15/16
n=-15/16:1/4
n=-15/16·4
n=-15/4

daca exercitiul tau este asa:
0,25·(n+1)=1/16
n+1=1/16:0,25
n+1=1/16 · 4
n+1=1/4
n=1/4 - 1
n=-3/4

(nu am inteles de ce ai pus in paranteze 0,25)
PS trebuie sa alegi rezolvarea in functie de cum e exercitiul tau. mai intreaba la comentarii daca nu e clar.

Answer 2

If...  (0,25)^(n+1) =1/16


[tex]\it 0,25=\dfrac{25}{100}^{(25}=\dfrac{1}{4} \\\;\\ \\\;\\ (0,25)^{n+1}=\dfrac{1}{16} \Leftrightarrow \left (\dfrac{1}{4}\right)^{n+1} = \left(\dfrac{1}{4}\right)^2 \Leftrightarrow n+1=2 \Leftrightarrow n=1[/tex]
