Question

answer please fast.............

Answer 1

HEya...!!!

(3 - √5)/(3+ 2√5)

=> (3 - √5)/(3 + 2√5) × (3 - 2√5)/(3 - 2√5)

=> (9 - 6√5 - 3√5 + 10)/(9 - 20)

=> (19 - 9√5)/(-11)

=> (19 - 9×2.236)/-11

=> -1.124/-11

=> 0.1022

Answer 2

$Given : \frac{3 - \sqrt{5} }{(3 + 2 \sqrt{5}) }$

$\frac{(3 - \sqrt{5} )(3 - 2 \sqrt{5}) }{(3 + 2 \sqrt{5} )(3 - 2 \sqrt{5}) }$

$\frac{3 * 3 - 3 * 2 \sqrt{5} - \sqrt{5} * 3 + \sqrt{5} * 2 \sqrt{5} }{3^2 - (2 \sqrt{5})^2 }$

$\frac{9 - 6 \sqrt{5} - 3 \sqrt{5} + 10 }{9 - 20}$

$\frac{9 - 9 \sqrt{5} + 10 }{-11}$

$\frac{19 - 9 \sqrt{5} }{-11}$

$\frac{9 \sqrt{5} - 19}{11}$

$\frac{9 * 2.236 - 19}{11}$

$\frac{1.12461}{11}$

0.10224.


Hope this helps!
