Hasil dari : a. √12(√2+√27) b. 2√2(√2+3√3) c. √27(√48-√27)

a. √12=2√3 → 2√3 ( √2+3√3)= 2√6 + 2(3)(3) = 2√6+ 18

b. 2√2(√2 +3√3)= 2(2) + 6√6 = 4+6√6

c.√27=3√3;√48=4√3 → 3√3( 4√3-3√3)
= 12(3) -27 = 36-27 = 9
Ingat √a* √a= a

Maaf kalau salah

Saya coba bantu jawab yah !

Penyelesaian :
---------------------

a. √12 (√2 + √27)
= √24 + √324
= √(4 × 6) + √324
= 2√6 + 18

b. 2√2 (√2 + 3√3)
= (2√2) (√2) + (2√2) (3√3)
= (2 × 2) + (2 × 3 × √6)
= 4 + 6√6

c. √27 (√48 - √27)
= √(9 × 3) (√(16 × 3) - √(9 × 3))
= 3√3 (4√3 - 3√3)
= (3 × 4 × 3) - (9 × 3)
= 36 - 27
= 9

Semoga bisa membantu
