product of two natural numbers is 3 . then , the sum of reciprocals of their squares is
"explanation : if the numbers are a , b , then ab = 3 , as 3 is a prime number , so a = 1 , b = 3 . 1 / a 2 + 1 / b 2 = 1 / 1 ( 2 ) + 1 / 3 ( 2 ) = 10 / 9 option a"
add(power(divide(const_1, const_1), const_2), power(divide(const_1, 3), const_2))
