Question

x + 1/x = 3 then find x^7 + 1/x^7 = ?​

Answer 1

Answer:

if x+1/x=3 then x=1/2

x⁷+1/x⁷

by putting the value of x we get:

=(1/2)⁷+1/(1/2)⁷

=1/128+128

=(128 + 16384)/128

=16512/128

=129

Step-by-step explanation:x+1/x=3

                                            x+1=3x

                                           3x-x=1

                                          2x=1

                                    therefore x=1/2

I hope this will help you.
