\( \sqrt{21}\approx4.583 \), which is slightly less than (4.59). Use more accurate estimation for close values.
Step 2
Why this answer is correct
The correct answer is A. \( \sqrt{21}<4.59 \). \( \sqrt{21}\approx4.583 \), which is slightly less than (4.59). Use more accurate estimation for close values.
Step 3
Exam Tip
\( \sqrt{21}\approx4.583 \), जो (4.59) से थोड़ा छोटा है। निकट मानों में अधिक सटीक अनुमान करें।
\( \sqrt{15}\approx3.873 \), which is slightly less than (3.88). Use more accurate estimation for close values.
Step 2
Why this answer is correct
The correct answer is B. \( \sqrt{15}<3.88 \). \( \sqrt{15}\approx3.873 \), which is slightly less than (3.88). Use more accurate estimation for close values.
Step 3
Exam Tip
\( \sqrt{15}\approx3.873 \), जो (3.88) से थोड़ा छोटा है। निकट मानों में अधिक सटीक अनुमान करें।
\( \sqrt{7}\approx2.646 \), so it is slightly less than (2.65). Compare close values to more decimal places.
Step 2
Why this answer is correct
The correct answer is A. \( \sqrt{7}<2.65 \). \( \sqrt{7}\approx2.646 \), so it is slightly less than (2.65). Compare close values to more decimal places.
Step 3
Exam Tip
\( \sqrt{7}\approx2.646 \), इसलिए यह (2.65) से थोड़ा छोटा है। निकट मानों में अधिक दशमलव स्थान तक तुलना करें।
