What is surd?

When numbers are left in root form to express their exact value they are known as surds. Surds are irrational as they are infinite numbers with recurring decimals. For example,

How to identify surd numbers?

As you know, surds are irrational numbers which mean they cannot be expressed in the form of fractions. We can identify a number as surd if it cannot be simplified to remove the square root.

Let’s evaluate a few numbers using examples.

Example:

√25, √32, √100, ∛81

Solution:

√25 = √ (5×5) = √5² = 5 ----------> is not a surd

√32 = √ (16×2) = 4√2 -----------> is a surd

√100 = √ (10×10) = 10 ------------> is not a surd

∛81 = ∛ (3×3×3×3) = ∛ (3³×3) = 3∛3 ------------> is a surd

Use number to surd calculator above to identify the surd for simple and complex root number.
