Passi tas-Soluzzjonijiet

Iddividi 12 b'\frac{\sqrt{10}}{5} billi timmultiplika 12 bir-reċiproku ta' \frac{\sqrt{10}}{5}.

$$\frac{12\times 5}{\sqrt{10}}-1.6\times 50$$

Immultiplika 12 u 5 biex tikseb 60.

$$\frac{60}{\sqrt{10}}-1.6\times 50$$

Irrazzjonalizza d-denominatur tal-\frac{60}{\sqrt{10}} billi timmultiplika in-numeratur u d-denominatur mill-\sqrt{10}.

$$\frac{60\sqrt{10}}{\left(\sqrt{10}\right)^{2}}-1.6\times 50$$

Il-kwadrat ta' \sqrt{10} huwa 10.

$$\frac{60\sqrt{10}}{10}-1.6\times 50$$

Iddividi 60\sqrt{10} b'10 biex tikseb6\sqrt{10}.

$$6\sqrt{10}-1.6\times 50$$

Immultiplika 1.6 u 50 biex tikseb 80.

$$6\sqrt{10}-80$$

Fattur

$$6 \sqrt{10} - 80 = -61.026334039$$
