which of the following cannot be the value of X+1/X, If X is a positive real integer
(a) 9/5
(b) 11/5
(c) 13/5
(d) 14/5​

Answer 1

Answer:

c)

Step-by-step explanation:

if we take x= 9/5

after solving it we get, value of x+1/x= 14/9

if we take x=11/5

after solving like it we get,x+1/x=16/9

if we take x =13/5

after Solving get value of x + 1/x=2

which is not a positive real integer

if we take x = 14/5

after Solving get value of x+1/1=19/9
