if n is a prime number greater than 4 , what is the remainder when n ^ 2 is divided by 12 ?
"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 4 , square it and see what would be the remainder upon division of it by 12 . n = 7 - - > n ^ 2 = 49 - - > remainder upon division 49 by 12 is 1 . answer : c ."
subtract(power(add(4, 2), 2), multiply(12, const_4))
