giúp vs ạ minh đag cần gấp!!!!!!!!!!

`1 . ` `(\sqrt{96x^5})/(\sqrt{24x})` `(x>0)`

`=` `\sqrt{4x^4}`

`=` `2x^2`

_______________________________________

`2 . ` `(\sqrt{18(x+1)^3})/(\sqrt{2}x+\sqrt{2})` `(x> -1)`

`=` `(\sqrt{18(x+1)^3})/(\sqrt{2}(x+1))`

`=` `(\sqrt{9(x+1)^3})/(x+1)`

`=` `(3(x+1)\sqrt{x+1})/(x+1)`

`=` `3\sqrt{x+1}`

_______________________________________

`3 . ` `(\sqrt{3x^4y^4})/(\sqrt{27x^2y^4})` `(x<0 , y>0)`

`=` `(\sqrt{x^2})/(\sqrt{9})`

`=` `x/(\sqrt{9})`

`=` `x/3`
