Question

if x= 5+√6
then find the value of x + 1/x ??

Explanation :-

Solution :- ​

Answer 1

Step-by-step explanation:

(5+√6) + 1/(5+√6)

= [(5+√6)^2+1] / (5+√6)

= (25+6+10√6+1)/(5+√6)

= (32+10√6) / (5+√6)

=(32+10√6) (5-√6) / (5+√6) (5-√6)

= (32+10√6) (5-√6) / (25 -6 )

= ( 32+10√6) (5-√6) / 19

Answer 2

given :

x=5 + root6

x+1/x = 5+root6+1 / 5+root6

=) 6+root6 / 5+root6
