Idon’t understand how to slice this problem

Step-by-step explanation:

[(20x^5y²)/(5x^-3y^7)]^-3

[(20/5)(x^5/x^-3)(y²/y^7)]^-3

[4(x^{5-(-3)})(y^{2-7})]^-3

[4(x^8)(y^-5)]^-3

[4(x^8)/(y^5)]^-3

1/[4(x^8)/(y^5)]³

1/([4(x^8)/(y^5)][4(x^8)/(y^5)][4(x^8)/(y^5)])

1/([2⁴(x^16)/(y^10)][2²(x^8)/(y^5)]

1/[(2^6)(x^24)(y^-15)]

(2^-6)(x^-24)(y^15)

(y^15)/(2^6x^24)

[(y^5)/(4x^8)]³

answer: i think it is (1,-2)

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.
