Question

What does this equal

Answer 1

7.1 × 10⁸

Explanation:

You must divide the diameter of Mars by the diameter of softball.

`(7*10^7):(0.098)=(7*10^7)/(0.098)=(7*10^7:7)/(0.098:7)=(10^7)/(0.014)\\\\=(10^7)/((14)/(1000))=10^7*(1000)/(14)=(10^7*10^3)/(14)=(10^(7+3))/(14)=(1)/(14)*10^(10)\\\\(1)/(14)\approx0.071\to(1)/(14)*10^(10)\approx0.071*10^(10)=0.071*10^2*10^8\\\\=7.1*10^8\\\\\text{Used}\ a^n* a^m=a^(n+m)`
