Question

simplify root 5-1/root 5+1=root 5+1/root 5-1

Answer 1

Given,
$\sqrt{5 - 1} \div \sqrt{5 + 1} = \sqrt{5 + 1} \div \sqrt{5 - 1 } \\ \\ = > \sqrt{5 - 1} \sqrt{5 - 1} = \sqrt{5 + 1} \sqrt{5 + 1 } \\ \\ = > 5 - 1 = 5 + 1 \\ \\ = > 4 = 6 \\ \\ = > 4 - 6 = 0 \\ \\ = > - 2 = 0 \\ \\ = > 2 = 0$

Step-by-step explanation:

=[√5-1/√5+1]+ [√5+1/√5-1]

=(√5-1)²+(√5+1)² / √5-1 *√5+1

=5+1-2√5+5+1+2√5/ √(5)²-1²

formula [a+b ] [a-b] =a²-b²

=12/5-1

=12/4

=3
