tolong dijawab yak no 5, 6, 7 pakai cara!!!

5) √24 ÷ √3
= √4 . 6 ÷ √3
= 2√6 ÷ √3
=( 2√6) × (√3)
----------------------
√3 × √3
= 2√18
------------
3
= 2 . 3√2
---------------
3
= 6√2
-----------
3
= 2√2 (A)

6) √27 - √12 + √243
= √9.3 - √4.3 + √81.3
= 3√3 - 2√3 + 9√3
= 10√3 (C)

7) (2 + 3√6)²
= 2² + 2.2.3√6 + (3√6)²
= 4 + 12√6 + 54
= 58 + 12√6 (A)
