8(45)-3/sqrt[3]{125+2(-2)^2} eching

$$\frac { 8 ( 45 ) - 3 } { \sqrt[ 3 ] { 125 } + 2 ( - 2 ) ^ { 2 } }$$

Baholash

$$\frac{357}{13}\approx 27,461538462$$

Yechim qadamlari

360 hosil qilish uchun 8 va 45 ni ko'paytirish.

$$\frac{360-3}{\sqrt[3]{125}+2\left(-2\right)^{2}}$$

357 olish uchun 360 dan 3 ni ayirish.

$$\frac{357}{\sqrt[3]{125}+2\left(-2\right)^{2}}$$

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

$$\frac{357}{5+2\left(-2\right)^{2}}$$

2 daraja ko‘rsatkichini -2 ga hisoblang va 4 ni qiymatni oling.

$$\frac{357}{5+2\times 4}$$

8 hosil qilish uchun 2 va 4 ni ko'paytirish.

$$\frac{357}{5+8}$$

13 olish uchun 5 va 8'ni qo'shing.

$$\frac{357}{13}$$

Omil

$$\frac{3 \cdot 7 \cdot 17}{13} = 27\frac{6}{13} = 27,46153846153846$$
