Question

Please simplify..

3^7 over 3^5

Answer 1

You would have..
3^7
---
3^5
This simplifies to 3^2 because you subtract the exponents and it leaves one on the bottom. 3^2=9
Hope this helps! :)

Answer 2

thank you very much! :)

Answer 3

Think of it like this:

3 x 3 x 3 x 3 x 3 x 3 x 3
---------------------
3 x 3 x 3 x 3 x 3

You can cross out the first five 3's on the top and bottom. That leaves you with 3 x 3, or 9. The answer is 9. :)

Answer 4

\[\frac{\cancel{3\times3\times3\times3\times3}\times3\times3}{\cancel{3\times3\times3\times3\times3}}\]
