This means that the answer to the square root of 123 will have an infinite number of decimals. Ahlukileoi and 2 others learned from this answer the square root of 100 and of 0 25 are both rational as they are finite numbers the square root of 100 being 10 and the square root of 0 25 being 0 5. Round the underlined digit 75 254. That is let be proof.
