Sederhanakanlah 1. √3(3+√12 =.. 2.(√2+√3) (√2+√3) =.. 3. (√3+√2) (√3-√2) =.. 4. √18 : √12 =.. Tolong dibantu.. Dan dijelaskan

1. /3(3+/12) =/3(3+/4×3)
= /3(3+2/3)
=3/3+2/9
= 3/3+ 2×3
= 6+3/3
2. (/2+/3)(/2+/3) = 2+/6+/6+3
= 5+2/6
3. (/3+/2)(/3-/2) = 3-/6+/6-2
= 1
4. /18 : / 12 = /2×9 : /3×4
= 3/2 : 2/3

Maaf ya kalo salah:)
Semoga membantu
