Which two square roots are used to estimate square root 5?

A. Square root 1 and square root 2.
B. Square root 2 and square root 4.
C. Square root 4 and square root 9.
D. Square root 9 and square root 16.
Is the answer B?
Thanks

I would say A because 2 is the square root of 4.

2*2=4

So the answer is A for the square root of 5

This is not one of your choices, but I'd use the square roots of 4 and 6.

Then what do I pick, A?

The square root of 5 is 2.24

The square root of 2 is 1.4
The square root of 4 is 2
The square root of 9 is 3

Probably C is the best answer.

Ok thank you, I just redid it and I can see that C is the answer.

You're welcome. :-)

the answers are

it might sound funny but they are

1 & 2 are wrong

To estimate the square root of 5, we can look for two perfect square numbers that are closest to 5.

Option A: Square root 1 and square root 2. The square root of 1 is 1, and the square root of 2 is approximately 1.41. However, neither of these numbers are very close to 5.

Option B: Square root 2 and square root 4. The square root of 2 is approximately 1.41, and the square root of 4 is 2. Both of these numbers are closer to 5 than the numbers in option A.

Option C: Square root 4 and square root 9. The square root of 4 is 2, and the square root of 9 is 3. Again, both of these numbers are larger than the square root of 5, so they are not suitable for estimation.

Option D: Square root 9 and square root 16. The square root of 9 is 3, and the square root of 16 is 4. Similar to option C, both of these numbers are larger than the square root of 5, so they are not good estimates.

Based on the analysis, the answer is B. The square roots of 2 and 4 can be used to estimate the square root of 5.
