Quantity A equals Quantity Bখ)
Relationship indeterminateগ)
Quantity B is greaterঘ)
Quantity A is greaterExplanation
Let y = 9/13. However, it is not meaningful to try to manually calculate y2 or y1/2 in this case. The relationship is not indeterminate because the uantities are given numbers. It is also clear that Quantity A does not equal Quantity B here. So, we need to ascertain whether y2 is greater than or less than y1/2 when 0 < y < 1. Note y2 < y when 0 < y < 1. Also y1/2 > y when 0 < y < 1. Therefore, y1/2 > y2 when 0 < y < 1 Thus, Quantity B is greater than ARelated questions
