Question

if x=√2+1 , find the value of x+1/x​

Answer 1

Answer:

The value of the expression is 2.83

Step-by-step explanation:

The value of x is given to be : x = √2 + 1

Now, we need to find the value of the given expression

x + 1/x

The value of the required expression can be found easily by substituting the value of x = √2 + 1 in the expression

So, The value is :

=x + 1/x

=(√2+1) + 1/(√2+1)

=[(√2+1)²+1]/(√2+1)

=[2+1+2√2+1]/(√2+1)

=[4+2√2]/(√2+1)

=2.83
