(1-sqrt[3]{-8})-(10^-4+1/10) eching

$$( 1 - \sqrt[ 3 ] { - 8 } ) - ( 10 ^ { - 4 } + \frac { 1 } { 10 } )$$

Baholash

$$\frac{28999}{10000}=2,8999$$

Yechim qadamlari

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

$$1-\left(-2\right)-\left(10^{-4}+\frac{1}{10}\right)$$

-2 ning teskarisi 2 ga teng.

$$1+2-\left(10^{-4}+\frac{1}{10}\right)$$

3 olish uchun 1 va 2'ni qo'shing.

$$3-\left(10^{-4}+\frac{1}{10}\right)$$

-4 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{10000} ni qiymatni oling.

$$3-\left(\frac{1}{10000}+\frac{1}{10}\right)$$

\frac{1001}{10000} olish uchun \frac{1}{10000} va \frac{1}{10}'ni qo'shing.

$$3-\frac{1001}{10000}$$

\frac{28999}{10000} olish uchun 3 dan \frac{1001}{10000} ni ayirish.

$$\frac{28999}{10000}$$

Omil

$$\frac{47 \cdot 617}{2 ^ {4} \cdot 5 ^ {4}} = 2\frac{8999}{10000} = 2,8999$$
