Like Radical Terms
Like terms are terms that have the same variables raised to the same
power. For example, 3y^{2} and 8y^{2} are like terms. Like radical terms
are
terms whose radical parts have the same index and the same radicand.
For example,
and
are like radical terms. Each radical has
index 3 and radicand 4x.
However,
and
are
not like radical terms because each
radical has a different index. In particular, one radical is a square root and
the other is a cube root.
