Question 11 Find the values of a and b in each of the following (i)5+2

1.	Question 11 Find the values of a and b in each of the following (i)5+2√37+4√3=a−6√3 (ii)3−√53+2√5=a√5−1911 (iii)√2+√33√2−2√3=2−b√6 (iv)7+√57−√5−7−√57+√5=a+711√5b
Answer» Question 11 Find the values of a and b in each of the following $(i) \frac{5 + 2 \sqrt{3}}{7 + 4 \sqrt{3}} = a - 6 \sqrt{3}$ $(i i) \frac{3 - \sqrt{5}}{3 + 2 \sqrt{5}} = a \sqrt{5} - \frac{19}{11}$ $(i i i) \frac{\sqrt{2} + \sqrt{3}}{3 \sqrt{2} - 2 \sqrt{3}} = 2 - b \sqrt{6}$ $(i v) \frac{7 + \sqrt{5}}{7 - \sqrt{5}} - \frac{7 - \sqrt{5}}{7 + \sqrt{5}} = a + \frac{7}{11} \sqrt{5} b$
