Passi tas-Soluzzjonijiet

Immultiplika 5 u 5 biex tikseb 25.

$$\frac{25}{2}+7\times 5\sqrt{2}-2$$

Immultiplika 7 u 5 biex tikseb 35.

$$\frac{25}{2}+35\sqrt{2}-2$$

Ikkonverti 2 fi frazzjoni \frac{4}{2}.

$$\frac{25}{2}+35\sqrt{2}-\frac{4}{2}$$

Billi \frac{25}{2} u \frac{4}{2} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{25-4}{2}+35\sqrt{2}$$

Naqqas 4 minn 25 biex tikseb 21.

$$\frac{21}{2}+35\sqrt{2}$$

Fattur

$$\frac{7 {(10 \sqrt{2} + 3)}}{2} = 59.99747468305833$$
