@Nurali could you help me out on this one?

anonymous · Answer

15x^6/20y^5 x 6y^2/5x^4

Is that correct?

anonymous · Answer

yes

anonymous · Answer

First you can simplify the constants

3x^6/4y^5 x 6y^2/5x^4

Then multiply it through

18x^6y^2/20x^4y&5

anonymous · Answer

so you multiply and then what do you do?

anonymous · Answer

This can be simplified further. When you divide powers, you subtract them. Sorry I was gone.

anonymous · Answer

It's okay

anonymous · Answer

This can be simplified to 9x^2/10y^3

Does that make sense?

anonymous · Answer

Yes it does, could you help with one more please? I'm sorry to take up so much of your time, im just really bad at math lol
