To simplify the expression, divide the coefficients and subtract the exponents of the variables with the same base:
start fraction, 5 x to the power 7 y to the power 8, divided by 125 x to the power 8 y to the power 5, end fraction
= (5/125) * (x^7/x^8) * (y^8/y^5)
= 1/25 * x^(7-8) * y^(8-5)
= 1/25 * x^(-1) * y^3
= y^3 / (25x)
Fully simplify using only positive exponents.
