Answer 3

To simplify the expression, let's calculate the values of the square roots first and then perform the subtraction:

1. Square root of 321: √321 ≈ 17.916472867168

2. Square root of 105: √105 ≈ 10.246950765959

Now, the expression becomes: 27 * √321 - 15 * √105

Substituting the approximate values: 27 * 17.916472867168 - 15 * 10.246950765959

Now, perform the calculations: 483.590634535536 - 153.704261489387

Finally, subtract the values: Result ≈ 329.886373046149

So, 27√321 - 15√105 ≈ 329.886373046149
