Answer 1

Answer:

3+2√5 / 3-2√5 × 3+2√5/3+2√5

(3+2√5)²/(3)²-(2√5)²

9+20+12√5/9-20

29+12√5/-11

-29/11 - 12√5/11

Answer 2

Answer:

= 29+12$\sqrt{5}$/-11

Step-by-step explanation:

here, 3+2$\sqrt{5}$/3-2$\sqrt{5}$

now, 3+2$\sqrt{5}$/3-2$\sqrt{5}$*3+2$\sqrt{5}$/3+2$\sqrt{5}$

     = 9+6$\sqrt{5}$+6$\sqrt{5}$+20/9-20

so, 29+12$\sqrt{5}$/-11
