Answer:

Option (3) is correct.

-27x^9+y^6 is the expression written as the sum of cubes as

(-3x^3)^3+(y^2)^3

Step-by-step explanation:

<u>Sum of cubes</u> : is defined as  a^3+b^3

We have to choose a sum of cubes from given expressions,

Consider -27x^9+y^6

Here  -27x^9 can be written as (-3x^3)^3

and y^6 can be written as (y^2)^3

Thus, -27x^9+y^6=(-3x^3)^3+(y^2)^3

Hence, -27x^9+y^6 is the expression written as the sum of cubes as (-3x^3)^3+(y^2)^3

Thus, option (3) is correct.
