Multiple choice general knowledge math & puzzles 12^3+2^3= 9^3 +10^3 Is this true ? True False Reveal answer Fill a bubble to check yourself B Correct answer Explanation 12^3 (1728) + 2^3 (8) = 1736. 9^3 (729) + 10^3 (1000) = 1729. Since 1736 does not equal 1729, the statement is false. This is a near-miss of the famous Ramanujan taxicab number (1729), which is 12^3 + 1^3.
