Question

Which is the best estimate for (8.9x10^8)/(3.3x10^4) written in scientific notation? A. 3x10^2 B. 6x10^2 C. 3x10^4 D. 6x10^4

Answer 1

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

Answer 2

Option C

Explanation:

The given expression is
`(8.9* 10^(8))/(3.3* 10^(4))`

Now we have to solve this.

`(8.9* 10^(8))/(3.3* 10^(4))`

`=(8.9)/(3.3)* (10^(8))/(10^(4))`

= 2.70 × 10⁽⁸⁻⁴⁾

= 2.70 × 10⁴

≈ 3 × 10⁴

Therefore, Option C is the answer.
