Question

if x=2+√3 then find the value of (x-1/x)​

Answer 1

Answer:

Step-by-step explanation:

Here,

x=2+√3

So, 1/x=1/(2+√3)

1/x=[1/(2+√3)][(2-√3)/(2-√3)]

1/x=(2-√3)/1

Therefore

1/x+x=2+√3+2-√3

=4

Answer 2

Given that x=2+√3

We should find x - 1/x

So the solution will be

x=2+√3

1/x = 1/2+√3 × ( 2√3)/(2-√3)

1/x = 2-√3

Now we will do

x-1/x

= 2+√3 + 2-√3

= 2 + 2

= 4
