Answer 1

`\text{the scientific notation}\\\\a\cdot10^n\ \text{where}\ 1\leq a < 10\ \text{and}\ n\in\mathbb{Z}`

`5\underbrace{7,909,000}_(\leftarrow7)km=5.7909\cdot10^7km\\\\1\underbrace{08,200,000}_(\leftarrow8)km=1.082\cdot10^8km\\\\1\underbrace{49,600,000}_(\leftarrow8)km=1.496\cdot10^8km\\\\2\underbrace{27,940,000}_(\leftarrow8)km=2.2794\cdot10^8km\\7\underbrace{78,330,000}_(\leftarrow8)km=7.7833\cdot10^8km\\\\1,\underbrace{424,600,000}_(\leftarrow9)km=1.4246\cdot10^9km\\\\4,\underbrace{498,252,900}_(\leftarrow9)km=4.4982529\cdot10^9km`
