n^2=17 eching

$$n ^ { 2 } = 17$$

n uchun yechish

$$n=\sqrt{17}\approx 4,123105626$$

$$n=-\sqrt{17}\approx -4,123105626$$

Kvadrat ildizini topish bo'yicha qadamlar

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

$$n=\sqrt{17} n=-\sqrt{17}$$

Kvadrat tenglamalaridan foydalanish qoidalari

Ikkala tarafdan 17 ni ayirish.

$$n^{2}-17=0$$

Ushbu tenglama standart shaklidadir: ax^{2}+bx+c=0. Kvadrat tenglama formulasida, \frac{-b±\sqrt{b^{2}-4ac}}{2a} 1 ni a, 0 ni b va -17 ni c bilan almashtiring.

$$n=\frac{0±\sqrt{0^{2}-4\left(-17\right)}}{2}$$

0 kvadratini chiqarish.

$$n=\frac{0±\sqrt{-4\left(-17\right)}}{2}$$

-4 ni -17 marotabaga ko'paytirish.

$$n=\frac{0±\sqrt{68}}{2}$$

68 ning kvadrat ildizini chiqarish.

$$n=\frac{0±2\sqrt{17}}{2}$$

n=\frac{0±2\sqrt{17}}{2} tenglamasini yeching, bunda ± musbat.

$$n=\sqrt{17}$$

n=\frac{0±2\sqrt{17}}{2} tenglamasini yeching, bunda ± manfiy.

$$n=-\sqrt{17}$$

Tenglama yechildi.

$$n=\sqrt{17} n=-\sqrt{17}$$
