Question

Need help with these two questions

Answer 1

Explanation:

Answer:(A)= (-x^11)/(y^7)

(B)= (1/12xy^5)

Explanation:

(A) (3x^3y^-2)(-2x^-3y^2)^-5/(6x^7y^-5)

[(3x^3y^-2)(-2x^15y^-10)]/(6x^7y^-5)

(6x^18y^5)/(-6x^7y^12)

(-6x^11)/(6y^7)

(-x^11)/(y^7)

(B) [(12x^-3y^5)/(x^-4)]^-1

(1/12xy^5)
