==============================================
Work Shown:
![(6 + √(27))/(3)\\\\(6 + √(9*3))/(3)\\\\(6 + √(9)*√(3))/(3)\\\\(6 + 3√(3))/(3)\\\\(3(2 + √(3)))/(3)\\\\2 + √(3)\\\\](https://img.qammunity.org/2021/formulas/mathematics/college/fb61r8pzshpfb86k9xqi7e03th6yh1bpsy.png)
The idea with simplifying the square root (steps 2 through 4) has us factoring 27 so that one factor is a perfect square. We want the largest perfect square factor possible.
That way when we use the rule sqrt(x*y) = sqrt(x)*sqrt(y), we pull out that perfect square to then use the rule sqrt(x^2) = x where x is nonnegative.
After simplifying the square root, we factor out the GCF and then cancel out the 3's.
