\[\frac{ A ^{r} }{ A ^{s} }=A ^{r-s}\]

Answer 2

hmm i dont know how

Answer 3

\[\large \frac{216x^2y^4}{27x^5y}=\frac{216y^3}{27x^3}\] is a start

Answer 4

okay thanks i'll do it from there

Answer 5

i got 8x^3 y^3

Answer 6

graph each system of constraints. name all vertices. then find the values of x and y that maximize or minimize the objective function.

x≤3
y≤7
x≥0, y≥0

How do I do it and am I supposed to graph each inequality or only one of them?
