Answer 1

Explanation:

You want the ratio of (7.785×10^10) to (1.5×10^8) expressed in standard form.

Division

Since you want the result in standard form, it can work well to make the numerator and denominator powers of ten be the same.

`(7.785*10^(10))/(1.5*10^8)=(7785*10^7)/(15*10^7)=(7785)/(15)=\boxed{519}`
