無理数 is the general term for irrational numbers, while 不尽根数 specifically refers to irrational numbers expressed as roots (surds).

Etymology

From 不尽 (fujin, 'inexhaustible' or 'endless') + 根 (kon, 'root') + 数 (sū, 'number'), reflecting the idea of a root that cannot be expressed as a terminating or repeating decimal.
