Given :   दो पूर्णांकों के वर्गमूल का योग √18 + 8√5 है

To Find :   पूर्णांकों के वर्गों का योग

Solution:

दो पूर्णांक  = a  , b

√a  + √b =   √18 + 8√5

=> √a  + √b =   3√2 + 8√5

Squaring both sides

=> a + b + 2√ab   =  18   + 320  +  48√10

=> a + b  + 2√ab = 338  + 48√10

=> a + b  = 338

2√ab =  48√10

=> √ab = 24√10

=> ab  = 5760

a + b  = 338  

Squaring both sides

=> a²  + b²  + 2ab  =  1,14,244

=> a²  + b²  + 2(5760) =   1,14,244

=>  a²  + b²   = 1,02,724

पूर्णांकों के वर्गों का योग   = 1,02,724
