Answer is 17/4
Solution
Let a and b be two nos
Given that a+b=55/22 =5/2
And ab=1
Then from (x+y)²=x²+y²+2xy
(5/2)²=a²+b²+2(1)
25/4=a²+b²+2
17/4=a²+b²

Answer
M² + N² = 17/4
Given that, sum of two numbers is 55/22.
Let us assume that, one number is M and other number is N.
So, their sum is written as M + N.
According to question,
.....(1)
Also given that, product of that numbers is 1. Means, product of assumed numbers i.e. M and M is 1.
.......(2)
We have to find the sum of squares of the assumed numbers.
Used identity: (a + b)² = a² + b² + 2ab
Substitute the known values
