2 और 3 के बीच दो परिमेय संख्याएँ ज्ञात कीजिए।

Q6. Simplify: \[ 16^{-\frac{1}{4}} \times \sqrt[4]{16} \]

सरल कीजिए: \[ 16^{-\frac{1}{4}} \times \sqrt[4]{16} \]

Q7. Find the value of x if \[ 3 + 2^x = 64^{\frac{1}{2}} + 27^{\frac{1}{3}} \]

यदि \[ 3 + 2^x = 64^{\frac{1}{2}} + 27^{\frac{1}{3}} \] हो, तो x का मान ज्ञात कीजिए।

Section C: Long Answer (3 Marks Each)

Q8. Determine rational numbers p and q if \[ \frac{7+\sqrt{5}}{7-\sqrt{5}} - \frac{7-\sqrt{5}}{7+\sqrt{5}} = p - 7\sqrt{5}\,q \]

यदि \[ \frac{7+\sqrt{5}}{7-\sqrt{5}} - \frac{7-\sqrt{5}}{7+\sqrt{5}} = p - 7\sqrt{5}\,q \] हो, तो p तथा q के मान ज्ञात कीजिए।

Q9. Simplify: \[ \frac{6}{2\sqrt{3}-\sqrt{6}} + \frac{\sqrt{6}}{\sqrt{3}+\sqrt{2}} - \frac{4\sqrt{3}}{\sqrt{6}-\sqrt{2}} \]

सरल कीजिए: \[ \frac{6}{2\sqrt{3}-\sqrt{6}} + \frac{\sqrt{6}}{\sqrt{3}+\sqrt{2}} - \frac{4\sqrt{3}}{\sqrt{6}-\sqrt{2}} \]

Q10. If x = 2 + 3√2, find the value of \[ \left(x + \frac{14}{x}\right) \]

यदि x = 2 + 3√2 हो, तो \[ \left(x + \frac{14}{x}\right) \] का मान ज्ञात कीजिए।
