Radical expressions are those in which the radical symbol (under root sign denoting the square root or the nth root) is present (either multiplied or added). Solving these is a bit tricky, but involves similar algebraic maneuvers in a different way. This video begins with an explanation of the general rules to be followed while solving such mathematical problems. The concept of simplified form and its importance is also explained. The later half of the video explains the concept once more with the help of solutions to two example problems. The application of the rules mentioned above is explained in this part.
