hello users ...

Given that:
x+1/x =66 

we have to find ;
(√x - 1/√x ) = ?

solution:-
we know that :
a
² + b² = ( a-b)² + 2ab

Here,
we can write ...
x+1/x  as (√x)² + (1/√x)² 

=> (√x)² + (1/√x)²  = (√x - 1/√x)² + 2 * √x * 1/√x 

=> 66 =  (√x - 1/√x)² + 2

=>  (√x - 1/√x)² = 66 - 2 = 64 

=>  (√x - 1/√x)²  = 8² 

=>  (√x - 1/√x) = 8 Answer 

# hope it helps :)
