To find x^{27}, we can solve this algebraically using the properties of polynomials:

Step 1: Rearrange the Equation

Starting from the given equation:

Rearranging terms gives:

Step 2: Use the Sum of Cubes Identity

Recall the sum of cubes factorization:

Since x² - x + 1 = 0, multiplying both sides by (x + 1) gives:

Step 3: Compute x^{27}

Now, express x^{27} in terms of x³:

Substitute x³ = -1:

Final Answer

-1
