Question

If x+1/x= 5, then find the value of √x+1/√x.​

Answer 1

Answer:

So the value of x+1/√x is (5 + √21)^3/2 + 2√2 / 2√(5 + √21 ).

Answer 2

Answer:

( x + 1 /x ) = 5

We need to find root x + 1 / root x

(root x + 1 / root x )^2= (root 5)^2

= rootx + 1 / rootx + 2 = 5

=root x+ 1 / rootx = 5 – 2

Hence, root x + 1 / root x= 3.
