Using rational approximations, what statement is true? (1 point)

• the square root of 48 > the square root of 36
• the square root of 49 < 7
• the square root of 48 < the square root of 36
• the square root of 49 > 7

1 answer

To evaluate the provided statements using rational approximations, we can analyze each one:

  1. The square root of 48 > the square root of 36

    • The square root of 36 is \(6\) (since \(6^2 = 36\)).
    • The square root of 48 is approximately \(6.93\) (since \(6.93^2 \approx 48\)).
    • So, \( \sqrt{48} > \sqrt{36} \) is true.
  2. The square root of 49 < 7

    • The square root of 49 is \(7\) (since \(7^2 = 49\)).
    • So, \( \sqrt{49} < 7 \) is false.
  3. The square root of 48 < the square root of 36

    • Since we established that \( \sqrt{48} > \sqrt{36} \), this statement is false.
  4. The square root of 49 > 7

    • Since \( \sqrt{49} = 7 \), this statement is false.

Therefore, the only true statement is: The square root of 48 > the square root of 36.
