“But each amoeba doubles each time,” Dani added. “Start: ( 4 ) → after 1 split: ( 4 \times 2 = 8 ), after 2 splits: ( 8 \times 2 = 16 ), etc. That’s ( 4 \times 2^6 ).”

I’d love to help, but I don’t have access to specific textbooks or their page numbers, including “Matematika kelas 9 halaman 55” (which appears to be an Indonesian Grade 9 math textbook). Page 55 could contain different topics depending on the publisher (e.g., Kemendikbud, Erlangga, Yudhistira). matematika kelas 9 halaman 55

“See?” Dani smiled. “We didn’t need page 55. We just needed to think like page 55.” “But each amoeba doubles each time,” Dani added

“Two hours = 120 minutes,” Rina calculated. “120 ÷ 20 = 6 divisions.” Page 55 could contain different topics depending on

However, I can create a short based on a typical math problem found at that level. Many Indonesian Grade 9 curricula around page 55 cover exponents (perpangkatan) or roots (bentuk akar) or possibly scientific notation .

Then they recalled a word problem: Sebuah amoeba membelah diri menjadi dua setiap 20 menit. Jika mula-mula ada 4 amoeba, berapa banyak setelah 2 jam? (“An amoeba splits into two every 20 minutes. Initially there are 4 amoeba, how many after 2 hours?”)
