What is the true statement regarding the difference between 2 times the square root of 7 and the square root of 28?

To analyze the statement regarding the difference between 2 times the square root of 7 and the square root of 28, we need to first express these quantities mathematically:

Step 1: Calculate each expression.

  • 2 times the square root of 7 is written as 2√7.
  • The square root of 28 can be simplified: √28 = √(4 × 7) = √4 × √7 = 2√7.

Step 2: Compare the two expressions.

Now we can easily see that:

  • 2√7 (which is the first expression) is equal to √28 (which simplifies to 2√7).

This means the difference between the two expressions, 2√7 – √28, can be calculated as follows:

  • Difference: 2√7 – 2√7 = 0.

Conclusion:

The true statement regarding the difference between 2 times the square root of 7 and the square root of 28 is that they are equal, leading to a difference of 0.
