यदि (P) संख्या रेखा पर \( \sqrt{196}-\sqrt{81} \) पर है, तो (P) का निर्देशांक क्या है?
If (P) is at \( \sqrt{196}-\sqrt{81} \) on the number line, what is the coordinate of (P)?
Explanation opens after your attempt
A. (5)
Concept
\( \sqrt{196}=14 \) and \( \sqrt{81}=9 \), so the difference is (5). Find each square root first.
Why this answer is correct
The correct answer is A. (5). \( \sqrt{196}=14 \) and \( \sqrt{81}=9 \), so the difference is (5). Find each square root first.
Exam Tip
\( \sqrt{196}=14 \) और \( \sqrt{81}=9 \), इसलिए अंतर (5) है। पहले अलग-अलग वर्गमूल निकालें।
