Ответ:
Choice A is correct.
Step-by-step explanation:
We have given the expression :
(x⁻⁴y/x⁻⁹y⁵)⁻²
We have to simplify it.
As we know that, a⁻¹ = 1/a
Apply it to the expression we get,
(x⁻⁹y⁵/x⁻⁴y)²
applying the whole power 2 to the nominator and the denominator and the nominator.
(x⁻⁹y⁵)²/(x⁻⁴y)²
ₓ⁻¹⁸y¹⁰/x⁻⁸y²
x⁻¹⁰y⁸
y⁸/x¹⁰ is the simplification.
Choice A is correct.
