Diketahui jari-jari planet Saturnus kira-kira 120.000 km dan jari-jari planet Merkurius kira-kira 2.440 km. Perbandingan diameter planet Saturnus dan Merkurius dalam bentuk notasi ilmiah, yaitu
![]()
Jawab:
Diameter Saturnus: 2r
= 2 x 120000
= 240000km
Diameter Merkurius: 2r
= 2 x 2440
= 4880km
Perbandingan:
Dia Saturnus : Dia Merkurius
= 240000km : 4880km
= 240000 : 4880
[tex] = 240000 \div 4880 \\ = (24 \times 10000) \div (488 \times 10) \\ = (24 \times {10}^{4} ) \div (488 \times 10) \\ = 2.4 \times {10}^{5} \div 4.88 \times {10}^{3} [/tex]
