Question

What polynomial identity should be used to prove that 133 = 125 + 8?

Answer 1

The correct answer for the given question above with the given polynomial is the last option: Sum of Cubes. Sum of cubes is the polynomial identity that can be used to prove that 133 = 125 + 8. Sum of cubes is the sum of a perfect cube and another perfect cube.

Answer 2

Answer:

D. Sum of cubes.

Step-by-step explanation:

We have been given an equation $133=125+8$. We are asked to choose the polynomial identity that should be used to prove our given equation.

We can rewrite $125$ as $5^3$ and $8$ as $2^3$.

Upon substituting these values in our given equation, we will get:

$133=5^3+2^3$

Therefore, we should use sum of cubes property to prove our given equation.
