Which is larger: eπe^\pi or πe\pi^e?

A

eπe^\pi (about 23.1)

B

πe\pi^e (about 22.5)

C

They are equal

D

Cannot determine

Correct Answer: A

Choice A is the correct answer. Calculate both values.

  1. Calculate eπe^\pi: e3.1415923.14e^{3.14159} \approx 23.14.
  2. Calculate πe\pi^e: 3.141592.71822.463.14159^{2.718} \approx 22.46.
  3. Comparison: 23.14>22.4623.14 > 22.46, so eπ>πee^\pi > \pi^e.

💡 Strategic Tip: This is a famous inequality: eπ>πee^\pi > \pi^e.

Choice B is incorrect becauseπe\pi^e is slightly smaller. Choice C is incorrect because they are close but not equal. Choice D is incorrect because we can calculate both.
