Sqrt 74 Estimate
1. The problem is to estimate the value of $\sqrt{74}$ without a calculator and determine between which two numbers it lies.
2. We know that $8^2 = 64$ and $9^2 = 81$. Since $74$ is between $64$ and $81$, $\sqrt{74}$ lies between $8$ and $9$.
3. To narrow it down further, check squares closer to 74:
- $8.5^2 = 72.25$
- $8.6^2 = 73.96$
- $8.7^2 = 75.69$
4. Since $74$ is greater than $73.96$ and less than $75.69$, $\sqrt{74}$ is between $8.6$ and $8.7$.
5. Therefore, $\sqrt{74}$ is between $8.5$ and $9$.
Final answer: The best statement is Choice B: The value of $\sqrt{74}$ is between $8.5$ and $9$.
