The objective is to create the square-root of a perfect square in the denominator; then simplify the whole fraction.
#1 4/sqrt3
Multiply top and bottom by sqrt3 to get:
[4sqrt3]/[sqrt9]
=4sqrt3/3
or
=(4/3)sqrt3
#2 -1/sqrt12
Multiply top and bottom by sqrt 3 to get:
[-sqrt3]/[sqrt(36)]
=[-sqrt3]/6
or
=(-1/6)sqrt3]
