Question

1²⁰¹⁷=2017^x-3

Answer 1

\(2017^{x-3}=1^{2013}\)

\(\Rightarrow2017^{x-3}=1\)

\(\Rightarrow x-3=0\)

\(\Rightarrow x=3\)

Answer 2

1²⁰¹⁷ = 2017^{x - 3}

=> 1 = 2017^{x - 3}

=> 2017⁰ = 2017^{x - 3}

=> x - 3 = 0

     x = 0 + 3

     x = 3

Vậy x = 3

k cho mk nhaaa

Answer 3

1²⁰¹⁷=2017^x-3

1      =2017^x:2017³

=>2017^x=2017³ =>x=3

  Vậy x=3

Answer 4

1²⁰¹⁷ = 2017^x-3

  1     = 2017^x-3

2017⁰ = 2017^x-3

 => 0 = x - 3 

 0 + 3 = x 

   3    = x 

Vậy 1²⁰¹⁷ = 2017^3-3
