A surd is any number whose nth root (square root, cube root, etc.) cannot be simplified so as to remove the radical sign, e.g., 2 and 4 3. Unless the radicand can be factorized into parts that are all perfectly expressible as a power of the radical’s index (perfect squares for square root, cubes for cube roots, etc.), the radical ...
