QuestionUse a calculator to approximate the square root. Check to see that the approximation is reasonable. $$\sqrt{72}$$ $\sqrt{72} \approx$ $\square$ (Round to the nearest thousandth as needed.)

Studdy Solution
Verify the approximation by squaring $8.485$ to check if it is close to $72$.
$$8.485^2 \approx 71.995225$$
Since $71.995225$ is close to $72$, the approximation is reasonable.
The approximation of $\sqrt{72}$ rounded to the nearest thousandth is:
$\boxed{8.485}$
