tolong yang bisa jawab ye please yooo

Dik:
fob = 1 cm
fok = 5 cm
d = 16 cm
Tanpa akomodasi
sn = 25 cm
Dit: M

Jawab:
M = | s'ob / sob| × | sn/fok|

Cari dl s'ob dan sob
d = s'ob + fok
16 = s'ob + 5
s'ob = 11

1/fob = 1/sob + 1/s'ob
1/sob = 1/1 + 1/11
1/sob = 11/11 + 1/11
s'ob = 11/12 cm

Jadi
M = [11 / (11/12)] × (25/5)]
M = 12 × 5
M = 60 Kali
