giúp mình câu 2,3,5,6 với ạ,gấp nha mn

`1)`

`(x-1)^3 = 1/8`

`<=> (x-1)^3 = (1/2)^3`

`=> x - 1 = 1/2`

`=> x = 3/2`

`2)`

`(3-x)^3 = -27/64`

`<=> (3-x)^3 = (-3/4)^3`

`=> 3 - x = -3/4`

`=> x = 15/4`

`3)`

`(x-5)^3 = (-1/27)`

`<=> (x-5)^3 = (-1/3)^3`

`<=> x - 5 = -1/3`

`=> x = 14/3`

`4)`

`(x-4)^2 = 4/9`

`<=> (x-4)^2 = (+- 2/3)^2`

`<=> x - 4 = +- 2/3`

`=> x = 14/3` hoặc `x = 10/3`

`5)`

`(5-x)^2 = 1/16`

`<=> (5-x)^2 = (+- 1/4)^2`

`<=> 5 - x = +- 1/4`

`<=> x = 21/4` hoặc `x = 19/4`

`6)`

`(x+1)^2 = 4/49`

`<=> (x+1)^2 = (+- 2/7 )^2`

`<=> x + 1 = +- 2/7`

`=> x = -5/7` hoặc `x = -9/7`
