Yechim qadamlari

Faktor: 12=3\times 4. \sqrt{3\times 4} koʻpaytmasining kvadrat ildizini \sqrt{3}\sqrt{4} kvadrat ildizlarining koʻpaytmasi sifatida qayta yozing.

$$15-2\sqrt{3}\sqrt{3}\sqrt{4}\times \frac{1}{2}$$

3 hosil qilish uchun \sqrt{3} va \sqrt{3} ni ko'paytirish.

$$15-2\times 3\sqrt{4}\times \frac{1}{2}$$

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$15-6\sqrt{4}\times \frac{1}{2}$$

4 ning kvadrat ildizini hisoblab, 2 natijaga ega bo‘ling.

$$15-6\times 2\times \frac{1}{2}$$

12 hosil qilish uchun 6 va 2 ni ko'paytirish.

$$15-12\times \frac{1}{2}$$

\frac{12}{2} hosil qilish uchun 12 va \frac{1}{2} ni ko'paytirish.

$$15-\frac{12}{2}$$

6 ni olish uchun 12 ni 2 ga bo‘ling.

$$15-6$$

9 olish uchun 15 dan 6 ni ayirish.

$$9$$
