Question

If x ≠ 0 and y ≠ 0, which expression is equivalent to −4x−2 y−3 ? Responses A −4x2y3 − 4 x 2 y 3 B 14x2y3 1 4 x 2 y 3 C −4x2y3 − 4 x 2 y 3 D −4xy − 4 xy

Answer 1

Answer:The expression −4x−2y−3 can be written as −4/x^2y^3.

Multiplying both numerator and denominator by -1, we get 4/x^2y^3.

Hence, option A, −4x^2y^3, is equivalent to −4x−2y−3.
