Tlong bantu jwb y no 1 dan no 2 mksih

Verified answer

1) 3√12 + 2√3 = 3√4.3 + 2√3
                       = 3.2√3 + 2√3
                       = 6√3 + 2√3
                       = 8√3

2) (27¹/²)²/³ = 27¹/³
                  = 3

MAPEL = MATEMATIKA
KELAS = 9
BAB = AKAR & PANGKAT

1.)
3√12 + 2√3
= 3√(4 × 3) + 2√3
= 6√3 + 2√3
= 8√3 ➡ C.

2.)
${ ({27}^{ \frac{1}{2} }) }^{ \frac{2}{3} } \\ = {(27)}^{ \frac{1}{2} \times \frac{2}{3} } \\ = {27}^{ \frac{2}{6} } \\ = {( {3}^{3} )}^{ \frac{2}{6} } \\ = {3}^{ \frac{2}{2} } \\ = {3}^{1} \\ = 3$
jawaban C.

semoga membantu
