In this lesson I discuss the second, very basic method for computing certain limits of sequences that involve a difference with radicals.<br><br> You will learn how to effortlessly distinguish the two versions (easier and harder) of limits that are solved using multiplication by the conjugate.<br><br> <h3>Table of Contents</h3> <ul> <li>overview: when we apply the method [01:30]</li> <li>multiplying by the conjugate with square roots – example 1 [02:41]</li> <li>multiplying by the conjugate with square roots – example 2 [07:48]</li> <li>multiplying by the conjugate with square roots – example 3 [10:31]</li> <li>multiplying by the conjugate with square roots – example 4 [14:24]</li> <li>multiplying by the conjugate with square roots – example 5 [20:27]</li> <li>multiplying by the conjugate with square roots – example 6 [24:11]</li> <li>multiplying by the conjugate with a cube root – example [27:56]</li> <li>using two methods at once – example [30:45]</li> </ul>
