Answer 2

To find the value of the expression, let's simplify each square root separately and then perform the operations step by step:

1. √16 = 4 (because 4 * 4 = 16)
2. √3 ≈ 1.732 (approximately, this is an irrational number)

Now, the expression becomes:

2 * 4 - 1.732 * √27

Next, simplify the square root of 27:

√27 = √(9 * 3) = √9 * √3 = 3 * √3 ≈ 3 * 1.732 ≈ 5.196 (approximately)

Now, the expression becomes:

2 * 4 - 1.732 * 5.196

Next, perform the operations:

8 - 8.99 ≈ -0.99 (approximately)

So, the value of the expression is approximately -0.99.
