Answer 1

Esitmate:
 9 /3 = 3
and
8-4 = 4
 so it would be 3x10^4
 answer is C

Answer 2

Answer:

Option C

Step-by-step explanation:

The given expression is$\frac{8.9\times 10^{8}}{3.3\times 10^{4}}$

Now we have to solve this.

$\frac{8.9\times 10^{8}}{3.3\times 10^{4}}$

$=\frac{8.9}{3.3}\times \frac{10^{8}}{10^{4}}$

= 2.70 × 10⁽⁸⁻⁴⁾

= 2.70 × 10⁴

≈  3 × 10⁴

Therefore, Option C is the answer.
