Multiple choice general knowledge math & puzzles x=1/9 colA : root(x)-x^2 colB : 0 Both columns are equal. True False Reveal answer Fill a bubble to check yourself B Correct answer Explanation Substituting x = 1/9: Column A = √(1/9) − (1/9)² = 1/3 − 1/81 = 27/81 − 1/81 = 26/81 ≈ 0.321. Since 26/81 > 0, Column A is greater than Column B. The statement that both columns are equal is false.
