Answer 2

No, Radical always not an irrational number.

Explanation:

√9 is radical.

But √9 = 3 which is not an irrational number.

Thus, Radical always not an irrational number.

Further,

Radical is the root of the number. It can be a square root, cube root, etc.

Example, √4, √7, ∛5, etc.

An irrational number has non-repeating, non-terminating decimal expansion and also we can not write an irrational number in a simple fraction. An irrational number is all real numbers except the rational number.

Example, √2, π, 6.458978445...., etc.
