Question

what is meant by under root

Answer 1

The square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16. The symbol is √ which always means the positive square root.

Answer 2

When you say under root it means nothing but taking the square root of the number.
