    1 is the cube of 1, as 1 * 1 * 1 = 1.

    64y^6 is the cube of 4y^2, as (4y^2)(4y^2)(4y^2) = 64y^6.

    Therefore, written as the sum of two cubes, 64y^6 + 1 is:

    (4y^2)^3 + 1^3.

    An equation needs to have two sides to it.

    As written, 64y^6 + 1 isn't an equation.

    However, if it is equal to something, such as 0, then it becomes an equation.

    64y^6 + 1 = 0 is an equation.
