Question

plz solve this question plzzzzz​

Answer 1

Answer:

7

Step-by-step explanation:

(a/b + b/a) = (a^2+ b^2)/ab

but ab is 1 therefore we have to find

(a^2 + b^2)

after multiplying rationalizing the denominator of a we will get

a= (6+2✓5)/4

b= 1/a= 4/(6+2✓5)

b= 4(6-2✓5)/16

b= (6-2✓5)/4

a+b =3

(a^2 + b^2) = (a+b)^2 - 2ab= 9-2= 7

answer is 7
