My professor gave us some homework. He asked us to prove witch is greater π^3 > 3^π or π^3 < 3^π using calculus? Typing it in the calculator tells me that 3^π is greater, but how do I prove this using calculus? All I need is some help or some one to point me in the right direction bcz I really don't understand how I prove this using calculus. What method should I use?
