Question

3-root 5 divided by 3+root 5 =root 5 -1 divide by 11 b

Answer 1

Answer:

$3 \sqrt{5 } \div( 3 + \sqrt{5) } = ( \ \sqrt{5} - 1) \div 11$

$3 \sqrt{5} (3 - \sqrt{5) } \times 11 = 5 \times ( \sqrt{5} - 1)$

$(9 \sqrt{5} - 15) \times 11 = 11 \sqrt{5} - 11$

$99 \sqrt{5} - 165 = 11 \sqrt{5} - 11$

$88 \sqrt{5} - 154$

$11(8 \sqrt{5} - 14)$
