Question

1) x²⁰¹⁹ - 1 = 0

2) x⁴ - 16 = 0

3) 32 - x⁵ = 0

4) ( x - 2 )³ = ( 1 - 3x )³

5) ( 4 - 3x )¹⁰ - ( 3 + x ) = 0

6) x² = x

7) x⁶ = x³

8) ( x - 3 )⁵  = 4 ( x - 3 )

Answer 1

1) x^​2019 ​-1 =0 => x^​2019 ​=1 => x=1

​

Answer 2

2) x⁴ -16 =0 => x^​4 ​=16 => x⁴ = 4⁴ hoặc (-4)⁴ => x = 4 hoặc -4

Answer 3

Trả lời

1)x²⁰¹⁹-1=0

=>x²⁰¹⁹   =0+1

=>x²⁰¹⁹   =1

=>x²⁰¹⁹  =1²⁰¹⁹

=>x=1

2)x⁴-16=0

=>x⁴    =0+16

=>x⁴    =16

=>x⁴    =2⁴

=>x=2

3)32-x⁵=0

=>x⁵    =32-0

=>x⁵    =32

=>x⁵     =2⁵

=>x=5

Answer 4

Tiếp nha !

4)(x-2)³=(1-3x)³

=>x-2   =1-3x

=>1x-2 =1-3x

=>4x    =1+2

=>4x    =3
