Videos on Square Root Simplification

a first use for primes and factorization of whole numbers

Here is a lesson on the cosmetic simplification of square roots of whole numbers without the use of decimal approximations.  The simplification is shown with or without the use of primes. Here computation may equal not the decimal approximation but the algebraic or cosmetic simplification of square roots. The examples below show how factorization and prime decomposition, together or not, may be used in the simplification process and also providing a stopping rule. See the videos.

In algebra, this simplification rewrites square roots in a standard form, a standard that may lead to a common representation of square roots of whole numbers when they appear in formulas and the derivation or justification of formulas.
