find out the square of a number which when doubled exceeds its one seventh by 13 ?
"a let the number be p , then the square will be p ^ 2 according to question : 2 p = ( p / 7 ) + 13 = > 14 p = p + 91 = > p = 7 p ^ 2 = 7 ^ 2 = 49 . answer : b"
power(divide(13, subtract(const_2, divide(const_1, add(const_4, const_1)))), const_2)
