Question

What is the square root of 17, rounded to the nearest tenth?

A) 4.1
B) 4.2
C) 4.0
D) 4.3

Answer 1

The square root of 17, rounded to the nearest tenth, is approximately 4.1, which is option A.

Step-by-step explanation:

The square root of 17, rounded to the nearest tenth, can be found using a scientific calculator. However, if we don't have one at hand, we can estimate by knowing that 4 squared (4²) is 16, and 5 squared (5²) is 25. Thus, the square root of 17 must be between 4 and 5. Since 17 is just one more than 16, we'd expect the square root of 17 to be just slightly more than 4. Rounding to the nearest tenth, the choices given are:

• A) 4.1
• B) 4.2
• C) 4.0
• D) 4.3

The closest estimate to the square root of 17 would then be 4.1, so the correct answer is A) 4.1.
