What's the next freak identity? A new deep connection with Sophie Germain primes

描述

The third video in a trilogy of Mathologer videos dealing with sum-equals-product identities and equations. The other two are: Way beyond the golden ratio The power of AB=A+B (Mathologer masterclass) https://youtu.be/cCXRUHUgvLI Heron’s formula: What is the hidden meaning of 1 + 2 + 3 = 1 x 2 x 3 ? https://youtu.be/IguNXoCjBEk Today's video is all about how 2+2=2x2 and 1+2+3=1x2x3 first extends to an infinite sequence of similar identities and then further to a whole world of sum-equals-product identities. And we chase down a new connection to the so-called Sophie Germain primes. 00:00 Int
