Product of two natural numbers is 17. Then, the sum of reciprocals of their squares is
If the numbers are a, b, then ab = 17, as 17 is a prime number, so the only possible values of a = 1 and b = 17. 1 a2 + 1 b2 = 1 12 + 1 172 = 1 + 1 289 = 289 +1 289 = 290 289
If the numbers are a, b, then ab = 17, as 17 is a prime number, so the only possible values of a = 1 and b = 17.
1 a2 + 1 b2
= 1 12 + 1 172
= 1 + 1 289 = 289 +1 289 = 290 289
