hello users ...
Given that:
x+1/x =66
we have to find ;
(√x - 1/√x ) = ?
solution:-
we know that :
a² + 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 :)
