Answer:
7.1 × 10⁸
Step-by-step explanation:
You must divide the diameter of Mars by the diameter of softball.
[tex](7\times10^7):(0.098)=\dfrac{7\times10^7}{0.098}=\dfrac{7\times10^7:7}{0.098:7}=\dfrac{10^7}{0.014}\\\\=\dfrac{10^7}{\frac{14}{1000}}=10^7\times\dfrac{1000}{14}=\dfrac{10^7\times10^3}{14}=\dfrac{10^{7+3}}{14}=\dfrac{1}{14}\times10^{10}\\\\\dfrac{1}{14}\approx0.071\to\dfrac{1}{14}\times10^{10}\approx0.071\times10^{10}=0.071\times10^2\times10^8\\\\=7.1\times10^8\\\\\text{Used}\ a^n\times a^m=a^{n+m}[/tex]
