|INDICES , SURDS AND SOME IDENTITIES
Here there are some formulae and identities which are helpful to students to solve
problems in algebra involving indices (powers), surds ( like square roots , cuberoots )
and identities to expand and factorise expressions.
[ A very common mistake is to just write the value of
(a + b)^2 as (a^2) + (b^2) instead of using the identity given below ]
