Passi tas-Soluzzjonijiet

Il-multiplikazzjoni tista' tiġi ttrasformata fid-differenza tal-kwadrati li jużaw ir-regola: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.

$$1^{2}-\left(8\sqrt{2}\right)^{2}$$

Ikkalkula 1 bil-power ta' 2 u tikseb 1.

$$1-\left(8\sqrt{2}\right)^{2}$$

Espandi \left(8\sqrt{2}\right)^{2}.

$$1-8^{2}\left(\sqrt{2}\right)^{2}$$

Ikkalkula 8 bil-power ta' 2 u tikseb 64.

$$1-64\left(\sqrt{2}\right)^{2}$$

Il-kwadrat ta' \sqrt{2} huwa 2.

$$1-64\times 2$$

Immultiplika 64 u 2 biex tikseb 128.

$$1-128$$

Naqqas 128 minn 1 biex tikseb -127.
