Radicals can only be added or subtracted when they have like radicands. a sqrt(x) + b sqrt(x) = (a+b) sqrt(x) asqrt(x)-bsqrt(x)=(a-b)sqrt(x) Since in our exercise all of the radicands are alike, we will use the Distributive Property to perform the addition.
4sqrt(3) + sqrt(3)
4sqrt(3) + 1sqrt(3)
(4+1)sqrt(3)
5sqrt(3)
