3^-0-{4}^-frac{1{2}}-{8}^-frac{2{3}} eching

$${ 3 }^{ -0 } - { 4 }^{ - \frac{ 1 }{ 2 } } - { 8 }^{ - \frac{ 2 }{ 3 } }$$

Baholash

$$\frac{1}{4}=0,25$$

Yechim qadamlari

0 daraja ko‘rsatkichini 3 ga hisoblang va 1 ni qiymatni oling.

$$1-4^{-\frac{1}{2}}-8^{-\frac{2}{3}}$$

-\frac{1}{2} daraja ko‘rsatkichini 4 ga hisoblang va \frac{1}{2} ni qiymatni oling.

$$1-\frac{1}{2}-8^{-\frac{2}{3}}$$

\frac{1}{2} olish uchun 1 dan \frac{1}{2} ni ayirish.

$$\frac{1}{2}-8^{-\frac{2}{3}}$$

-\frac{2}{3} daraja ko‘rsatkichini 8 ga hisoblang va \frac{1}{4} ni qiymatni oling.

$$\frac{1}{2}-\frac{1}{4}$$

\frac{1}{4} olish uchun \frac{1}{2} dan \frac{1}{4} ni ayirish.

$$\frac{1}{4}$$

Omil

$$\frac{1}{2 ^ {2}} = 0,25$$
