The simplified radical expression of 126 is 3 roots of 14. 126 can be divided by the perfect square nine, fourteen times. As a result you have 3 roots of 14.
Radical(27) can be simplified to 3*radical(3), so the correct answer is 6*radical(3).
Radical (3x) = radical(x) * radical(3).

An expression such as root(3) + 2 (square root of 3, added to 2) can not be simplified. Of course, you can convert the square root to a decimal and then add, to get an approximate result.
sqrt(27) = sqrt(9*3) = sqrt(9)*sqrt(3) = 3*sqrt(3)

sqrt(147) = sqrt(49*3) = sqrt(49)*sqrt(3) = 7*sqrt(3)

radical(48)/radical(3) = radical(48/3) = radical(16) = 4 Technically, radical(16) is +4 OR -4 but in such questions often only the principal root is required.
