Question

Tìm x biết:

(x-2010)⁴=81

Answer 1

\(\left(x-2010\right)^4=81\)

\(\left(x-2010\right)^4=\sqrt[4]{81}\)

\(\left(x-2010\right)=3\)

 \(x=3+2010\)

 \(x=2013\)

Answer 2

\(\left(x-2010\right)^4=81\\=>x-2010=3\\ =>x=2013 \)

Answer 3

Ta có: 81= 3.3.3.3= 3⁴

=> ( x- 2010)⁴ = 3⁴

=> x- 2010= 3

=> x= 3+ 2010

=> x= 2013

Vậy x= 2013

Answer 4

Ta có:

(x - 2010)⁴ = 3⁴

=> x - 2010 = -3  hoặc x - 2010 = 3

  =>       x     = 2007  hoặc   x   = 2013

Answer 5

(x-2010)⁴=81

=>(x-2010)⁴=3⁴ hoặc (-3)⁴

=>x-2010=3 hoặc -3

Xét x-2010=3

=>x=2013

Xét x-2010=-3

=>x=2007
