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.

IDENTITIES

indices, surds and identities= (a+b)(a-b)

[ 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 ]
