To estimate 0.207 21 × 3.86 ​ , I rounded the values for simplicity: 21 remains 21, 3.86 rounds to 4, and 0.207 rounds to 0.2. After performing the calculation, the estimated value is approximately 420.

Jawaban:1. 0,000869 km = ... cm- 1 km = 100.000 cm- 0,000869 km = 0,000869 × 100.000 cm = 86,9 cm2. 0,0001234 m = ... mm- 1 m = 1000 mm- 0,0001234 m = 0,0001234 × 1000 mm = 0,1234 mm3. 0,1852 cm = ... m- 1 m = 100 cm- 0,1852 cm = 0,1852 / 100 m = 0,001852 m4. 286.000168 n = ... m- Sepertinya ada kesalahan dalam soal ini. "n" biasanya digunakan untuk Newton (satuan gaya), bukan satuan panjang. Jika maksudnya adalah nanometer (nm), maka:- 1 m = 1.000.000.000 nm- 286.000168 nm = 286.000168 / 1.000.000.000 m = 0,000286000168 m5. 288 km/jam = ... m/s- 1 km = 1000 m- 1 jam = 3600 detik- 288 km/jam = (288 * 1000) / 3600 m/s = 288000 / 3600 m/s = 80 m/s maka, jawabannya yaitu:1. 86,9 cm2. 0,1234 mm3. 0,001852 m4. 0,000286000168 m (dengan asumsi "n" adalah nanometer)5. 80 m/s
