During the second week of Foundations of Mathematics and Pre-Calculus 10, I learned how to convert a entire radical into a mixed, with a index of 2. You can convert a entire radical into a mixed by finding the highest perfect square and factoring it out. This equals to the coefficient. Then you multiply the coefficient by the radical whatever number is left. Note: always simplify, if you convert a entire radical into a mixed, and if the radicand can be factored by a perfect square still, simplify it by taking it out the radicand and multiply by the coefficient again.
