Answer 2

To solve the expression (12³ - 9³) : (12 - 9), we can follow the order of operations, which states that we should perform any calculations within parentheses first, followed by exponents (or powers), and then perform multiplication and division from left to right.

Let's simplify the expression step by step:

1. Evaluate the expression within the parentheses: (12³ - 9³) = (1728 - 729). This simplifies to (999).

2. Divide the result by the expression outside the parentheses: (999) : (12 - 9). Since 12 - 9 equals 3, we have (999) : 3.

3. Perform the division: (999) : 3 = 333.

Therefore, the value of (12³ - 9³) : (12 - 9) is 333.

I hope this helps!
