<PRE><B>Question 49984</B>
a. 40 X^8 Y^6 / 5 XY^3

a. What we need to do in this case is look at all of the different parts of the equation separately

40/5,x^8/x, and y^6/y^3

Now simplify
40/5=8
x^8/x=x^7  (*remember x^a/x^b=x^a-b)
y^6/y^3=y^3

so now put them together again!
8x^7y^3

now im not 100% sure on the second equation and it is quite hard to explain how to figure it out online so, if i can i will but now i cant
-soo sorry</PRE>
