Question

x^8 y^12 / x^4 y^4
x=2 y=-1

Answer 1

(x^8 y^12) / (x^4 y^4) =

x ^ (8-4) * y ^ (12-4) =

x^4 / y ^ 8

Check this work for accuracy.

Then subsitute 2 for x and -1 for y.

Answer 2

yes

Answer 3

Then subsitute 2 for x and -1 for y.

Answer 4

is that the answer

Answer 5

If you simplify the equation you get (x^4)*(y^8) so then you substitute 2 for x and -1 for y
