Algebraic Numbers
Real numbers that
can occur as roots of polynomial equations that have integer coefficients.
For example, all
rational numbers are
algebraic. So are all surds such
as \(\sqrt 7 \), as well as numbers built from surds such as the number below.
\[\frac{{42 + \sqrt[3]{{15.2}}}}{{\sqrt {4  \sqrt 3 } }}\].
Note: Real numbers which are not algebraic
are known as transcendental
numbers.
