Answer:


√(72)


√(201)


√(52)

These are surd

so A and D are not surd

Explanation:

A surd is an expression that includes a square root, cube root or other root symbol. Surds are used to write irrational numbers precisely – because the decimals of irrational numbers do not terminate or recur, they cannot be written exactly in decimal form.
