Question

X+1/x=2 ,x^2019+1/x^2020=?

Answer 1

Answer:

Answer is 2

Step-by-step explanation:

We have given that         X + 1/X =2

                                  now we assume here what value of X will satisfy this equation that is given to us.

                                 only we have 1 + 1/1 = 2 means we have value of X = 1 that is satisfying this equation

so putting the value of X = 1 in         X^2019 + 1/X ^2019

                                                            1^2019 + 1/1^2019

                                                            = 2

note : in this type of equation always look to the equation that is satisfying the value and assume value according to the question and put that particular value.
