Answer:

If we write the final answer with negative exponents, then it will be:

(x^-7)(y^-4)

If we write this as a fraction, it will be:

1/(x^7)(y^4)

Step-by-step explanation:

x^-3 is equivalent to 1/x^3. We can put this in the denominator expression and calculate the product:

[tex]\frac{y^{2} }{(x^4)(x^3)(y^6)}[/tex]    This simplifies into:

[tex]\frac{y^{2} }{(x^7)(y^6)}[/tex]    after the denominator simplifies.

If we write the final answer with negative exponents, then it will be:

(x^-7)(y^-4)

If we write this as a fraction, it will be:

1/(x^7)(y^4)
