Question: Contoh: Soal : 1. ( 3 / 9^-1 )^2 2. 4^-3 x 4^2 / 2 Yang sudah dipelajari: Graph/shape: a large handwritten parenthesized fraction is centered-left on the page, with numerator "3" over denominator "9^-1", and a superscript "2" at the upper right of the closing parenthesis; position_hint = center-left. Graph/shape: a handwritten fraction is on the right side, with numerator "4^-3 x 4^2" over denominator "2"; position_hint = center-right. User: apa jawaban dari gambar itu?
1. Mari kita selesaikan soal pertama: $$\left( \frac{3}{9^{-1}} \right)^2$$ 2. Ingat bahwa $$9^{-1} = \frac{1}{9}$$, jadi: $$\frac{3}{9^{-1}} = 3 \times 9 = 27$$ 3. Sekarang pangkatkan hasilnya dengan 2: $$27^2 = 729$$ --- 4. Soal kedua: $$\frac{4^{-3} \times 4^2}{2}$$ 5. Gunakan aturan pangkat untuk perkalian dengan basis sama: $$4^{-3} \times 4^2 = 4^{-3+2} = 4^{-1} = \frac{1}{4}$$ 6. Jadi ekspresi menjadi: $$\frac{\frac{1}{4}}{2} = \frac{1}{4} \times \frac{1}{2} = \frac{1}{8}$$ --- **Jawaban akhir:** 1. $$729$$ 2. $$\frac{1}{8}$$
