product of two natural numbers is 5 . then , the sum of reciprocals of their squares is
"explanation : if the numbers are a , b , then ab = 5 , as 17 is a prime number , so a = 1 , b = 5 . 1 / a 2 + 1 / b 2 = 1 / 1 ( 2 ) + 1 / 5 ( 2 ) = 26 / 25 option b"
add(power(divide(const_1, const_1), const_2), power(divide(const_1, 5), const_2))
