Issolvi t=290-300/50/sqrt{15}

$$t = \frac { 290 - 300 } { 50 / \sqrt { 15 } }$$

Solvi għal t

$$t=-\frac{\sqrt{15}}{5}\approx -0.774596669$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Naqqas 300 minn 290 biex tikseb -10.

$$t=\frac{-10}{\frac{50}{\sqrt{15}}}$$

Irrazzjonalizza d-denominatur tal-\frac{50}{\sqrt{15}} billi timmultiplika in-numeratur u d-denominatur mill-\sqrt{15}.

$$t=\frac{-10}{\frac{50\sqrt{15}}{\left(\sqrt{15}\right)^{2}}}$$

Il-kwadrat ta' \sqrt{15} huwa 15.

$$t=\frac{-10}{\frac{50\sqrt{15}}{15}}$$

Iddividi 50\sqrt{15} b'15 biex tikseb\frac{10}{3}\sqrt{15}.

$$t=\frac{-10}{\frac{10}{3}\sqrt{15}}$$

Irrazzjonalizza d-denominatur tal-\frac{-10}{\frac{10}{3}\sqrt{15}} billi timmultiplika in-numeratur u d-denominatur mill-\sqrt{15}.

$$t=\frac{-10\sqrt{15}}{\frac{10}{3}\left(\sqrt{15}\right)^{2}}$$

Il-kwadrat ta' \sqrt{15} huwa 15.

$$t=\frac{-10\sqrt{15}}{\frac{10}{3}\times 15}$$

Annulla 5 fin-numeratur u d-denominatur.

$$t=\frac{-2\sqrt{15}}{3\times \frac{10}{3}}$$

Annulla 3 u 3.

$$t=\frac{-2\sqrt{15}}{10}$$

Iddividi -2\sqrt{15} b'10 biex tikseb-\frac{1}{5}\sqrt{15}.

$$t=-\frac{1}{5}\sqrt{15}$$

Assenja t

$$t≔-\frac{\sqrt{15}}{5}$$
