Factorial-Power Selfie Expressions

This work brings numbers in such a way that both sides of the expressions are with same digits. One side is digits with factorial and another side are with same digits with respective powers. These types of expressions, we call as selfie expressions. Many ways of these types of expressions are studied. For distinct and … Continue reading Factorial-Power Selfie Expressions

Selfie Numbers and Binomial Coefficients

During past years, author studied different types of "selfie numbers", with extra operations as, factorial, square-root, Fibonacci sequence values, etc. This paper brings "selfie numbers" in terms of "binomial coefficients". This has been done in digit's order, reverse order of digits and in both ways. The results are limited to five digits. See below some examples:   … Continue reading Selfie Numbers and Binomial Coefficients
