Which is the best estimate for written in scientific notation?





I'm assuming you mean which one is written properly? It would be either 3 x 10^4 or 6 x 10^4.
Hope it helps!
For this case we have the following expression:
[tex] \frac{8.9*10^8}{3.3*10^4} [/tex]
Rewriting the expression we have:
[tex] \frac{8.9}{3.3} \frac{10^8}{10^4} [/tex]
For power properties we have:
In the division, Same base the exponents are subtracted
We have then:
[tex] \frac{8.9}{3.3}*10^{8-4} [/tex]
[tex] \frac{8.9}{3.3}*10^{4} [/tex]
[tex] 3*10^{4} [/tex]
Answer:
The best approach in scientific notation is given by:
[tex] 3*10^{4} [/tex]
