surds
In mathematics, we often arrive at answers that contain root signs (they may be square roots, cube roots, etc.).
We will find that some of these numbers with a root sign are easy to deal with since they have an exact decimal representation
For instance sqrt16 = 4, rt^3(8)= = 2, sqrt11.56 = 3.4, rt^5(1/32) = 0.5.
This is because each of these numbers is rational

Expressions with root signs involving pirrational numbers such as sqrt7 - 2 or rt^3(5) are called surds.
