if n is a prime number greater than 5 , what is the remainder when n ^ 2 is divided by 23 ?
"there are several algebraic ways to solve this question including the one under the spoiler . but the easiest way is as follows : since we can not have two correct answersjust pick a prime greater than 5 , square it and see what would be the remainder upon division of it by 23 . n = 5 - - > n ^ 2 = 49 - - > remainder upon division 49 by 23 is 3 . answer : d ."
subtract(power(add(5, 2), 2), multiply(23, const_4))
