Question

Using rational approximations, what is an inequality statement comparing 21−−√ and 17−−√ ? Enter <, >, or =.(1 point) The inequality is: 21−−√ 17−−√ .

Answer 1

To compare \( \sqrt{21} \) and \( \sqrt{17} \), we can compare their squares instead. This is because the square function is monotonically increasing for positive numbers:

1. Calculate the squares:
- \( \sqrt{21}^2 = 21 \)
- \( \sqrt{17}^2 = 17 \)

2. Now compare the squared numbers:
- Since \( 21 > 17 \), it follows that \( \sqrt{21} > \sqrt{17} \).

Thus, the inequality is:

\[
\sqrt{21} > \sqrt{17}
\]

So the answer is:
