If A=(1+ 1/38)^38 And B=(1 + 1/37)^37 Then 1) A=B, 2) A>B, 3) A>4, 4) A Sujoy Das 07/02/2018 3 0 0 Answer: Method 1: A = [(k + 1)/k ]^k B = [(k/(k - 1)]^(k - 1) Apply PMI now to get : A > B Method 2: Solution: (1+ 1/n)^n = e ~ 2.78xx.. as n tends to infinity. Now its an increasing function because just check for A = (1 +1/2)^2 and B= (1 +1)^1 ==> A= 9/4= 2.25 and B=2. So clearly A>B here. So, as the function is increasing so, it will also satisfy for our given A and B. i.e., A>B here. f(x)= (1 + 1/x)^x is alwz an increasing function. and as it is increasing function so, if x> y then f(x) > f(y) alwz. It also satisfies from here.
