Final answer:
The expression 64g² + 8 is already in its simplest form and cannot be factored further using standard algebraic identities or factoring techniques since the two terms have no common factor and the expression does not match any special factoring patterns.
The correct option is not given.
Step-by-step explanation:
The factored form of 64g² + 8 is not represented by any of the given options (A, B, C, D). The given expression is the sum of two terms, and such a sum cannot be factored in the standard way using algebraic identities or factoring techniques because there is no common factor between 64g² and 8, and it does not fit the pattern of a sum of cubes or a sum of squares.
Therefore, the original expression 64g² + 8 is already in its simplest form. When looking at the equation in terms of significant figures or as a quadratic equation, the given expressions do not seem to match or apply to the original question.
The correct option is not given.
