Question 57482
{{{sqrt(12)-sqrt(50)+sqrt(72)}}} You can only add radicals with the same index, so let's simplify, find factors that are perfect squares:
{{{sqrt(4)*sqrt(3)-sqrt(25)*sqrt(2)+sqrt(36)*sqrt(2)}}}  Take the square roots of the perfect squares
{{{2sqrt(3)-5sqrt(2)+6sqrt(2)}}}  Combine the numbers with like radicals.
{{{2sqrt(3)+sqrt(2)}}}
Happy Calculating!!!
