Question

√5+1/√5-1
im still a bit confused somebody help please

Answer 1

Multiply numerator and denominator by sqrt5 + 1

Answer 2

\[(\sqrt{5}+1)(\sqrt{5}+1)/(\sqrt{5}-1)(\sqrt{5}+1)\]

Multiplying, you get:
\[(5+2\sqrt{5}+1)/(5-1)\]
Which gives you
\[(6+2\sqrt{5})/(4)\]
which reduces to
\[(3+\sqrt{5})/2\]

Answer 3

i get what you did right there but in the end that can be simplified further should i do it or leave it like that?
