What is the value of \(2\sqrt{3}\times 3\sqrt{3}\)?(2\sqrt{3}\times 3\sqrt{3}) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(18\)\(18\)
Multiply the coefficients and the surd parts separately: \(2\times 3\times \sqrt{3}\times\sqrt{3}=6\times 3=18\), since \(\sqrt{3}\times\sqrt{3}=3\). Therefore, \(18\) is correct. Exam tip: \(\sqrt{a}\times\sqrt{a}=a\) for \(a\geq 0\).गुणांकों और करणी पदों को अलग-अलग गुणा करें: \(2\times 3\times \sqrt{3}\times\sqrt{3}=6\times 3=18\), क्योंकि \(\sqrt{3}\times\sqrt{3}=3\)। इसलिए सही उत्तर \(18\) है। परीक्षा में याद रखें: \(\sqrt{a}\times\sqrt{a}=a\) जब \(a\geq 0\) हो।
