Answer 3

To calculate the expression (12 * 12 * 12 - 9 * 9 * 9) / (12 - 9), we need to follow the order of operations, which is often represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. Start with the parentheses: There are no parentheses in the expression.

2. Next, perform the exponentiation: Again, there are no exponents in the expression.

3. Move on to multiplication and division, from left to right: Calculate 12 * 12 * 12 and 9 * 9 * 9: 12 * 12 * 12 = 1,728 9 * 9 * 9 = 729

4. Perform the division: Divide the result of the first multiplication (1,728) by the second multiplication (729): 1,728 / 729 = 2.37 (rounded to two decimal places)

Therefore, the value of the expression (12 * 12 * 12 - 9 * 9 * 9) / (12 - 9) is approximately 2.37.
