Question

Ifx=7-4√3find the value of x+1/x

Answer 1

Answer:

here is the answer to this equation

Step-by-step explanation:

If x=7+4√3 then

1/x=7–4√3/(7+4√3)(7–4√3)

1/x=7–4√3/49–48=7–4√3

Now(√x+1/√x)^2=x+1/x+2

=>7+4√3+7–4√3+2=16

(√x+1/√x)^2=16

Taking square root√x+1/√x=4

hope this answer really helps you in solving this equation
