On the number line, \(\sqrt{9}\) is the same as which point?संख्या-रेखा (number line) पर \(\sqrt{9}\) किस बिंदु के बराबर है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(3\)\(3\)
\(\sqrt{9}\) means the principal (non-negative) square root of \(9\). Since \(3^2=9\) and square roots are non-negative, \(\sqrt{9}=3\). So the point is \(3\).\(\sqrt{9}\) का अर्थ \(9\) का principal (अऋणात्मक) वर्गमूल है। क्योंकि \(3^2=9\) और वर्गमूल हमेशा अऋणात्मक होते हैं, इसलिए \(\sqrt{9}=3\)। अतः बिंदु \(3\) है।
