solution (Question: 364660.0 )

the given question is in the form of, {(a^4)+(b^4)+(a^2)(b^2)}/{(a^2)+(b^2)+ab
where, a=5/2,b=3/5
now the numerator can be broken as,
(a^2+b^2)^2 -2(a^2)(b^2)+(a^2)(b^2)
=(a^2+b^2)^2-(a^2)(b^2) [now this is in the form of a^2 - b^2,so]
we will get one factor same as the denominator, so we are left with
a^2+b^2-ab
putting the values of and b we get 511/100
