SOLUTION: How would you solve these? I think you would rationalize the denominator first, is that right? These are two radical problems. {{{ 2 / (sqrt(3)-sqrt(5)) }}} {{{ 2 / sqrt(6)

------
Multiply numerator and denominator by (sqrt(3)+sqrt(5)) to get:
-------
= [2(sqrt(3)+sqrt(5))]/ [3-5]
----
= -(sqrt(3)+sqrt(5))
============================
Ratioalize the denominator of the 1st fraction:
[2sqrt(6)/6] + [3/4]
------
= sqrt(6)/3 + 3/4
-----
-----
= [4sqrt(6) + 3*3]/12
----
= [4sqrt(6)+9]/12
=======================
cheers,

There's nothing to solve, no variable.

Multiply the NUM and DEN by the conjugate of the DEN
