Answer 2

To solve the given expressions, let's simplify them step by step:

1. 16² - 9²: 16² means 16 raised to the power of 2, which is equal to 16 * 16 = 256. 9² means 9 raised to the power of 2, which is equal to 9 * 9 = 81.

   Therefore, 16² - 9² = 256 - 81 = 175.

2. 16² + 2 × 16 × 9 + 9²: Similarly, 16² = 256 and 9² = 81.

   Now, let's calculate 2 × 16 × 9: 2 × 16 × 9 = 32 × 9 = 288.

   Finally, we can substitute the values into the expression: 16² + 2 × 16 × 9 + 9² = 256 + 288 + 81 = 625.

Therefore, the values of the given expressions are:

1. 16² - 9² = 175.
2. 16² + 2 × 16 × 9 + 9² = 625.
