Describe how you would simplify the given expression.
To simplify the expression, first simplify inside the parentheses by dividing the coefficients (20/5 = 4) and subtracting the exponents for each base (5 - (-3) = 8 for x, and 2 - 7 = -5 for y), which results in 4x^8y^-5. Next, raise the resulting expression to the -3 power by multiplying the exponents (8 * -3 = -24 and -5 * -3 = 15). Finally, rewrite the expression using positive exponents. Alternatively, you could first raise the numerator and denominator to the -3 power using the power of a power property, then divide coefficients and subtract exponents.
