How would you solve this? the simplest way I thought about was by using the binomial expansion. (1+X)^n = 1 +nX + n(n-1) X2/2!+ ....... (n=200, X= 0.005) The additional positive terms after 1 + nX (200*0.005) will make it larger than 2. was curious to see other ways of thinking about it1yr ⋅ TheBellJar11 ⋅ r/askmath
