Question

Giúp mình với √12-√75+√27

Answer 1

`sqrt{12}-sqrt{75}+sqrt{27}`

`=sqrt{4.3}-sqrt{25.3}+sqrt{9.3}`

`=2sqrt3-5sqrt3+3sqrt3=0`

Answer 2

Ta có : \(\sqrt{12}-\sqrt{75}+\sqrt{27}=2\sqrt{3}-5\sqrt{3}+3\sqrt{3}=0\)

Answer 3

Ta có: \(\sqrt{12}-\sqrt{75}+\sqrt{27}\)

\(=2\sqrt{3}-5\sqrt{3}+3\sqrt{3}\)

=0
