How to solve difficult SSC CGL level Surd Algebra problems in a few steps 4 video

Three difficult SSC CGL level surd algebra problems are solved in a few steps using most of the surd algebra problem solving techniques in this 4th session of algebra solving in quick steps. The first problem is solved using double square root surd simplification technique and surd factoring technique. Standard surd comparison technique is applied to solve the second problem and to solve the large surd simplification third problem, two often ignored but important numerator simplification techniques are applied along with the general principle of selecting the more complex term to eliminate. With these approaches, all three problems can easily be solved in mind by an experienced problem solver. The concepts and methods should prove valuable additionally for SSC CGL Tier II, CAT or GMAT where algebra is a topic...

thumb_how-to-solve-surds-part-3-surd-expression-comparison-and-ranking

In this third tutorial on how to solve surd problems, we will take up explaining two related problem classes, namely, two-term surd expression comparison and ranking. First we will state and explain two important rich concepts used for quick solution and then apply the rich concepts in solving chosen SSC CGL level problems...

How to solve Surds part 2, double square root surds and surd term factoring

thumb_how-to-solve-surds-part-2-double-square-root-surds

In this second tutorial we will explain how a surd expression under a second square root is dealt with as well as explain two other typical surd problem solving techniques, namely, surd term factoring and coefficient equalization of surd and non-surd terms in a surd equation. We will explain through the process of solving chosen SSC CGL level problems...
