Question

evaluate the expression (3n - 4)³ when n = 2. which part of the expression will you evaluate first? 4³ n - 4 3n

Explanation:

To evaluate \((3n - 4)^3\) when \(n = 2\), we follow the order of operations (PEMDAS/BODMAS). The expression inside the parentheses \((3n - 4)\) must be simplified first. Within the parentheses, we perform multiplication before subtraction (since multiplication has higher precedence than subtraction in the order of operations). So we first evaluate \(3n\) (which is \(3\times n\)) as the multiplication part inside the parentheses. The other options: \(4^3\) is outside the parentheses evaluation step here, and \(n - 4\) would skip the multiplication of \(3\) and \(n\) which is incorrect as per order of operations.

Answer:

\(3n\)
