GUYS I NEED HELPPPPPPPPPP
3x^6y^9 I think
\[\frac{ 9x^5y^8 }{ 3xy}=3x^5y^8x^{-1}y^{-1}=3x^{5-1}y^{8-1}=3x^4y^7\]
I swear I think thats 3x^4 y^7
I do not know
I haven't done this in a while
it is very simple and it is corrct.
You can subtract the exponents in the numerator by those in the denominator, as long as they belong to the same variable. Basically: \[\frac{x^{a}}{x^{b}} = x^{a-b}\] So we can look at each part, the first is 9/3, which just comes out to three. Now your equation should look like this: \[\frac{3x^{5}y^{8}}{xy}\] Using the property I mentioned, we should be able to subtract the exponents for both the x and the y... \[3x^{5-1}y^{8-1}\] Now simplify to get your final equation, and remember that if a variable has no exponent (meaning just an x or y) then there is actually a 1 there that should be used in problems like these. Have a great day!
