Dr.Peterson replied to the thread SURFACE AREA OF COMPOSITE SOLID..More important, the answer isn't relevant to the actual question; there is no"outer curved surface", because it is not a "hollow... -
Rrad_2007 replied to the thread Conjecture: n² divides Σ_{k=1..n} (2^k-2)/k numerator iff n is prime.No, not yet! But it should be posted there. But I'm so thankful to you. Especially what you did for the manipulation...

Ffresh_42 replied to the thread Conjecture: n² divides Σ_{k=1..n} (2^k-2)/k numerator iff n is prime.I'm not convinced yet how difficult it really is. I'm trying to use 2^n-1=\sum_{j=0}^{n-1} 2^{j}=\sum_{k=1}^n \binom n...

Sscottbrandon replied to the thread Help with quiz.You find 𝑐 c, 𝑛 n, 𝑚 m, and 𝑑 d by rearranging the first equation so it matches the second formula. Once it’s in that form, 𝑐 c is the...

Rrad_2007 replied to the thread Conjecture: n² divides Σ_{k=1..n} (2^k-2)/k numerator iff n is prime.Thanks for your valuable insights! The conjecture I proposed is supported by extensive computation up to 10^7 with no counterexamples...

Ffresh_42 replied to the thread Conjecture: n² divides Σ_{k=1..n} (2^k-2)/k numerator iff n is prime.This sounds as if you should dive deep into the theory of Mersenne numbers. If true, it also provides a primality test. However, there...
