Yechim qadamlari

2 daraja ko‘rsatkichini 1 ga hisoblang va 1 ni qiymatni oling.

$$-1-\left(-2\right)^{3}\times \frac{1}{8}-\sqrt[3]{27}|-\frac{1}{3}|+\frac{2}{\left(\sqrt{2}\right)^{2}}$$

3 daraja ko‘rsatkichini -2 ga hisoblang va -8 ni qiymatni oling.

$$-1-\left(-8\times \frac{1}{8}\right)-\sqrt[3]{27}|-\frac{1}{3}|+\frac{2}{\left(\sqrt{2}\right)^{2}}$$

-1 hosil qilish uchun -8 va \frac{1}{8} ni ko'paytirish.

$$-1-\left(-1\right)-\sqrt[3]{27}|-\frac{1}{3}|+\frac{2}{\left(\sqrt{2}\right)^{2}}$$

-1 ning teskarisi 1 ga teng.

$$-1+1-\sqrt[3]{27}|-\frac{1}{3}|+\frac{2}{\left(\sqrt{2}\right)^{2}}$$

0 olish uchun -1 va 1'ni qo'shing.

$$0-\sqrt[3]{27}|-\frac{1}{3}|+\frac{2}{\left(\sqrt{2}\right)^{2}}$$

\sqrt[3]{27} ni hisoblab, 3 natijasiga ega bo‘ling.

$$0-3|-\frac{1}{3}|+\frac{2}{\left(\sqrt{2}\right)^{2}}$$

a haqiqiy sonining mutloq qiymati qachon a\geq 0 bo‘lganda, a yoki qachon a<0 bo‘lganda -a. -\frac{1}{3} ning mutloq qiymati \frac{1}{3} ga teng.

$$0-3\times \frac{1}{3}+\frac{2}{\left(\sqrt{2}\right)^{2}}$$

1 hosil qilish uchun 3 va \frac{1}{3} ni ko'paytirish.

$$0-1+\frac{2}{\left(\sqrt{2}\right)^{2}}$$

-1 olish uchun 0 dan 1 ni ayirish.

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

\sqrt{2} kvadrati – 2.

$$-1+\frac{2}{2}$$

1 ni olish uchun 2 ni 2 ga bo‘ling.

$$-1+1$$

0 olish uchun -1 va 1'ni qo'shing.
