What is the value of \(\sqrt{1.44}\)?\(\sqrt{1.44}\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 1.21.2
Since \(1.2^2=1.2\times1.2=1.44\), we have \(\sqrt{1.44}=1.2\). The principal square root is always taken as non-negative. The other options are incorrect because \(0.12^2=0.0144\), \(1.02^2=1.0404\), and \(12^2=144\). As an exam tip, square the proposed answer to check the decimal placement.क्योंकि \(1.2^2=1.2\times1.2=1.44\), इसलिए \(\sqrt{1.44}=1.2\)। वर्गमूल का मुख्य मान सदैव गैर-ऋणात्मक लिया जाता है। अन्य विकल्पों में \(0.12^2=0.0144\), \(1.02^2=1.0404\) और \(12^2=144\) होते हैं। परीक्षा में दशमलव का स्थान जाँचने के लिए प्राप्त उत्तर का वर्ग कर लें।
