Sederhanakanlah!1. √18 + 3√50 – 2 √12 =2. 2√3 (5√3 -√2) =

1 )
= √18 + 3√50 – 2√12
= 3√2 + 6√2 – 4√3
= 9√2 – 4√3

2)
= 2√3 (5√3 – √2)
= 30 – 2√6

1). √18 + 3√50 – 2√12
= √9×2 + 3√25×2 – 2√4×3
= 3√2 + 3×5√2 – 2×2√3
= 3√2 + 15√2 -4√3
= 18√2 -4√3.

2). 2√3 (5√3 -√2)
=10×3 -2√6
= 30 – 2√6

Ket :
⚫️√a + √a = 2√a
⚫️√a x √a = a
⚫️√a x √b = √ab

Semoga membantu 🙂
