Step 2

Önce verilen ifadeyi tahtaya yazalım.

$$ \frac{5\sqrt[3]{48} - \sqrt[3]{6}}{\sqrt[3]{3} \cdot \sqrt[3]{2}}$$
3
Step 3

Pay kısmındaki kök kırk sekizi düzenleyerek başlayalım. Kırk sekiz sayısını sekiz çarpı altı şeklinde yazabiliriz.

$$ \sqrt[3]{48} = \sqrt[3]{8 \cdot 6}$$
$$ \sqrt[3]{48} = \sqrt[3]{8} \cdot \sqrt[3]{6}$$
4
Step 4

Sekiz sayısı iki küpüdür, bu yüzden kök dışına iki olarak çıkar.

$$ \sqrt[3]{48} = 2\sqrt[3]{6}$$
5
Step 5

Şimdi pay kısmını tekrar düzenleyelim. Beş çarpı iki küpkök altı eksi küpkök altı işlemi on küpkök altı eksi küpkök altı halini alır.

$$ 5(2\sqrt[3]{6}) - \sqrt[3]{6} = 10\sqrt[3]{6} - \sqrt[3]{6}$$
$$ 9\sqrt[3]{6}$$
