Question

if x + 1/x = 7 then find root of x/1 + root of x

Answer 1

Answer:

x + 1/x = 7

(root x +root 1/x)^2

x+1/x + 2rootx×root1/x

x+1/x+2

we know the value of x +1/x

7+2=9=(rootx+1/rootx)^2

rootx+1/rootx=3

Answer 2

X + 1/x = 7
Add 2 both side
x +1/x + 2 = 7+2
“ (rootx +1/rootx )^2 = 9
Square root both side
Root x + 1/rootx = 3 ans
