Hello Mate!

$i) \frac{1}{ \sqrt{6} + \sqrt{5} } \times \frac{ \sqrt{6} - \sqrt{5} }{ \sqrt{6} - \sqrt{5} } \\ \frac{ \sqrt{6} - \sqrt{5} }{6 - 5} = \sqrt{6} - \sqrt{5} \\ 2.45 - 2.24 = 0.21 \\ ii) \frac{6}{ \sqrt{5} + \sqrt{3} } \times \frac{ \sqrt{5} - \sqrt{3} }{ \sqrt{5} - \sqrt{3} } \\ \frac{6( \sqrt{5 } - \sqrt{3}) }{2} = 3 \sqrt{5} - 3 \sqrt{3} \\ or \\ 3( \sqrt{5} - \sqrt{3} ) = 3(2.45 - 1.73) \\ = 3 \times 0.72 = 2.16 \\ iii)\frac{1}{4 \sqrt{3} - 3 \sqrt{5} } \times \frac{4 \sqrt{3} + 3 \sqrt{5} }{4 \sqrt{3} + 3 \sqrt{5} } = \\ \frac{4 \sqrt{3} + 3 \sqrt{5} }{48 - 45} = \frac{4 \times 1.73 + 3 \times 2.24}{3} \\ = \frac{6.92 + 6.72}{3} = \frac{13.64}{3} = 4.54$

Pinge me out for any confusion ✌
