Tolong jawab dengan cara!!!​

1. 2√72 + 5√8 =

=2√36×2 + 5√4×2

=2×6 √2 + 5×2 √2

=12√2 + 10√2 = 22√2

2. √81 – 3√36 =

= 9 – (3×6)

= 9 – 18 = -9

3. 2√12 x 3√32 =

= 2√4×3 x 3√16×2

= 2×2√3 x 3×4√2

= 4√3 x 12√2 = 48√6

4. 3√16 x √24 : √30 =

= 12 x 2√6 : √5 x √6

= 24/√5

semoga membantu 🙂

maaf jika salah
