Answer:
-6(√3 - 2)
Explanation:
Which did you mean?
6/[sqr(3) + 2]
or
6/(sqr(3)+2)
or what? Ambiguous unless you use parentheses.
If you meant
6/[sqr(3) + 2]
then rationalize the denominator by multiplying numerator and denominator of the given expression by (√3 - 2):
6(√3 - 2) 6(√3 - 2)
-------------------------- = ----------------- = -6(√3 - 2)
[sqr(3) + 2](√3 - 2) 3 - 4
