Yechim qadamlari

120 hosil qilish uchun 15 va 8 ni ko'paytirish.

$$2-\frac{\sqrt[3]{\frac{120+5}{8}}\sqrt{\frac{4}{25}}}{3}\sqrt[3]{27}+\left(-\sqrt{0\times 64}\right)\sqrt{400}$$

125 olish uchun 120 va 5'ni qo'shing.

$$2-\frac{\sqrt[3]{\frac{125}{8}}\sqrt{\frac{4}{25}}}{3}\sqrt[3]{27}+\left(-\sqrt{0\times 64}\right)\sqrt{400}$$

\sqrt[3]{\frac{125}{8}} ni hisoblab, \frac{5}{2} natijasiga ega bo‘ling.

$$2-\frac{\frac{5}{2}\sqrt{\frac{4}{25}}}{3}\sqrt[3]{27}+\left(-\sqrt{0\times 64}\right)\sqrt{400}$$

\frac{4}{25} boʻlinmasining kvadrat ildizini \frac{\sqrt{4}}{\sqrt{25}} kvadrat ildizlarining boʻlinmasi sifatida qayta yozing. Surat va maxrajni kvadrat ildizdan chiqaring.

$$2-\frac{\frac{5}{2}\times \frac{2}{5}}{3}\sqrt[3]{27}+\left(-\sqrt{0\times 64}\right)\sqrt{400}$$

1 hosil qilish uchun \frac{5}{2} va \frac{2}{5} ni ko'paytirish.

$$2-\frac{1}{3}\sqrt[3]{27}+\left(-\sqrt{0\times 64}\right)\sqrt{400}$$

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

$$2-\frac{1}{3}\times 3+\left(-\sqrt{0\times 64}\right)\sqrt{400}$$

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

$$2-1+\left(-\sqrt{0\times 64}\right)\sqrt{400}$$

1 olish uchun 2 dan 1 ni ayirish.

$$1+\left(-\sqrt{0\times 64}\right)\sqrt{400}$$

0 hosil qilish uchun 0 va 64 ni ko'paytirish.

$$1+\left(-\sqrt{0}\right)\sqrt{400}$$

0 ning kvadrat ildizini hisoblab, 0 natijaga ega bo‘ling.

$$1+0\sqrt{400}$$

400 ning kvadrat ildizini hisoblab, 20 natijaga ega bo‘ling.

$$1+0\times 20$$

0 hosil qilish uchun 0 va 20 ni ko'paytirish.

$$1+0$$

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