tlng dibantu pakai jalannya :-)

[tex]4 \sqrt{12} - 2 \sqrt{75} \\ = 4 \sqrt{4 \times 3} - 2 \sqrt{25 \times 3} \\ = 4.2 \sqrt{3} - 2.5 \sqrt{3} \\ = 8 \sqrt{3} - 10 \sqrt{3} [/tex]
[tex] = (8 - 10) \sqrt{3} \\ = -2 \sqrt{3} [/tex]

jawabannya A

maaf jika salah..

4√12 - 2√75
=4 √4 + √3 - 2 √25 + √3
=(4x2) √3 - (2x5) √3
= (8 - 10) √3
= a. -2√3
