Which is the simplified form of the expression (x^-3)(y^2)/(x^4)(y^6)

Pls mark Brainliest.

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:

   This simplifies into:

   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)

a) her total is 1

b) the cards could have any total, but most likely is something like 3 and -3
