Fully simplify using only positive exponents.

start fraction, 25, x, to the power 4 , y, squared, divided by, 25, x, to the power 7 , y, cubed, end fraction

To fully simplify this expression, we can use the laws of exponents:

Start with the numerator:
25x^4y^2

Divide by the denominator:
25x^7y^3

Now, let's use the law of exponents that states when dividing like bases, you subtract the exponents:

25x^(4-7) y^(2-3)

Simplifying the exponents:

25x^(-3) y^(-1)

Lastly, since we want only positive exponents, we can bring the negative exponents to the denominator:

25 / (x^3y)
