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...

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...

SSC CGL level Solution Set 57, Algebra 13


This is the 57th solution set of 10 practice problem exercise for SSC CGL exam and 13th on topic Algebra. For maximum gains, the test should be taken first, that is obvious. But more importantly, to absorb the concepts, techniques and deductive reasoning elaborated through these solutions, one must solve many problems in a systematic manner using this conceptual analytical approach. One can learn well only by practicing learning by doing...
