The answer is 8/(19683y^3)819683y3.

Explanation:

You have to use the power of a product rule:

(xy)^a=x^ay^a(xy)a=xaya

Here's the actual problem:

((6x^3)^2(6y^3))/((9xy)^6)(6x3)2(6y3)(9xy)6

((6^2(x^3)^2)(6y^3))/((9xy)^6)(62(x3)2)(6y3)(9xy)6

((36x^6)(6y^3))/((9xy)^6)(36x6)(6y3)(9xy)6

(216x^6y^3)/((9xy)^6)216x6y3(9xy)6

(216x^6y^3)/(9^6x^6y^6)216x6y396x6y6

(216x^6y^3)/(531441x^6y^6)216x6y3531441x6y6

(8color(red)(cancel(color(black)(x^6)))y^3)/(19683color(red)(cancel(color(black)(x^6)))y^6)

(8color(red)(cancel(color(black)(y^3))))/(531441y^(color(red)(cancel(color(black)(6)))3))

8/(19683y^3)

Unfortunately, this big fraction can't be simplified any further.
