Answer 2

To simplify the expression (9x + 2) - 3 and then raise it to the cube, follow these steps:

Step 1: Simplify the expression (9x + 2) - 3. (9x + 2) - 3 = 9x + 2 - 3 = 9x - 1.

Step 2: Raise the simplified expression to the cube. (9x - 1)^3 = (9x - 1) * (9x - 1) * (9x - 1).

Now, to find the result, we can expand the cube using the binomial expansion formula or simply multiply it out:

(9x - 1) * (9x - 1) * (9x - 1) = (81x^2 - 9x - 9x + 1) * (9x - 1) = (81x^2 - 18x + 1) * (9x - 1) = 729x^3 - 162x^2 + 9x - 9x^2 + 18x - 1 = 729x^3 - 171x^2 + 27x - 1.

So, the final answer after raising (9x + 2) - 3 to the cube is 729x^3 - 171x^2 + 27x - 1.
