검증된 단계별 안내1
Identify the given polynomial: \(x^{3} + 64\).
Recognize that \(64\) can be written as \$4^{3}\(, so the polynomial is \)x^{3} + 4^{3}$.
Recall that a sum of cubes has the general form \(a^{3} + b^{3}\), where both terms are perfect cubes.
Compare the polynomial to the sum of cubes form and confirm that it matches because both \(x^{3}\) and \$4^{3}$ are cubes.
Conclude that the polynomial \(x^{3} + 64\) is an example of a sum of cubes.
