To compare the values of 21−−√ and 17−−√ using rational approximations, we can use the fact that √21 is approximately 4.58 and √17 is approximately 4.12. Hence, we have:
√21 ≈ 4.58
√17 ≈ 4.12
Since 4.58 > 4.12, we can conclude that:
21−−√ > 17−−√
Using rational approximations, what is an inequality statement comparing 21−−√ and 17−−√? Enter <, >, or =.(1 point)
