HELP ITS DUE REALLY SOON!!!​

Answer 1

`\frac{8.4 * {10}^(10) }{3 * {10}^(7) } \\ = (8.4)/(3) * \frac{ {10}^(10) }{ {10}^(7) } \\ = 2.8 * {10}^(3) \\ = \boxed{2800}`

2800 is the right answer.

Answer 2

Explanation:

(8.4 * x * 10¹⁰) / (3 * x * 10⁷)

= (8.4/3) * (x/x) * (10¹⁰/10⁷)

= 2.8 * 1 * 10³

= 2.8 * 10³.
