Answer:

The answer is 26.

Step-by-step explanation:

Given :

n - y = 2 and ny =3

According to question,

we put the given formula ( n-y) ^ 3

=> (n-y) ^ 3 = n^ 3 - y^3 - 3ny(n-y)

=> 2^3 = n^ 3 - y^ 3 - 3 ×3×2

=> 8 = n^ 3 - y^ 3 - 18

=> 8 + 18 = n^3- y^ 3

=> n^3 - y^3 = 26

.... hope it help you
