Question

the product of two natural number is 29.Find the sum of the squares of their reciprocals?​

Answer 1

let x and y be the no.

x * y = 29

to find is

1/x + 1/y

x+y/xy

x+y/29

now as x × y = 29 and 29 is a prime no.

it's only possible when one of both no. be 1

so let x = 1

y=29

x + y/29

=30/29 is correct
