Rationalize the denominator and express in simplest form.
Please help me solve this problem. 4+ sqrt(5) /3- sqrt(5)
----------------------
[4+sqrt(5)]/[3-sqrt(5)]
Multiply numerator and denominator by 3+sqrt(5) to get:
----
[(4+sqrt(5)(3+sqrt(5)]/[9-5]
------
[12 + 5 + 7sqrt(5)]/4
------
[17+7sqrt(5)]/4
------------------------
