If \(x=\frac{\sqrt{144}}{5}\), which number represents \(x\) on the number line?यदि \(x=\frac{\sqrt{144}}{5}\), तो संख्या रेखा पर \(x\) का निरूपण किस संख्या द्वारा होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\frac{12}{5}\)\(\frac{12}{5}\)
Since \(\sqrt{144}=12\), we get \(x=\frac{12}{5}\). Therefore, \(x\) is represented by the point \(\frac{12}{5}\) on the number line. Exam tip: simplify the square root first and then divide by 5; \(\frac{144}{5}\) results from skipping the square-root step.क्योंकि \(\sqrt{144}=12\), इसलिए \(x=\frac{12}{5}\) होगा। अतः संख्या रेखा पर \(x\) को \(\frac{12}{5}\) के बिंदु द्वारा दर्शाया जाएगा। परीक्षा में पहले पूर्ण वर्ग का वर्गमूल निकालें और फिर प्राप्त संख्या को हर 5 से भाग दें; \(\frac{144}{5}\) में वर्गमूल निकालने के चरण को छोड़ दिया गया है।
