Yechim qadamlari

2 daraja ko‘rsatkichini 7 ga hisoblang va 49 ni qiymatni oling.

$$49\left(2-3+6\right)-64^{\frac{1}{3}}\left(6+3+2\left(4+2\right)^{2}-1-1\right)$$

-1 olish uchun 2 dan 3 ni ayirish.

$$49\left(-1+6\right)-64^{\frac{1}{3}}\left(6+3+2\left(4+2\right)^{2}-1-1\right)$$

5 olish uchun -1 va 6'ni qo'shing.

$$49\times 5-64^{\frac{1}{3}}\left(6+3+2\left(4+2\right)^{2}-1-1\right)$$

245 hosil qilish uchun 49 va 5 ni ko'paytirish.

$$245-64^{\frac{1}{3}}\left(6+3+2\left(4+2\right)^{2}-1-1\right)$$

\frac{1}{3} daraja ko‘rsatkichini 64 ga hisoblang va 4 ni qiymatni oling.

$$245-4\left(6+3+2\left(4+2\right)^{2}-1-1\right)$$

9 olish uchun 6 va 3'ni qo'shing.

$$245-4\left(9+2\left(4+2\right)^{2}-1-1\right)$$

6 olish uchun 4 va 2'ni qo'shing.

$$245-4\left(9+2\times 6^{2}-1-1\right)$$

2 daraja ko‘rsatkichini 6 ga hisoblang va 36 ni qiymatni oling.

$$245-4\left(9+2\times 36-1-1\right)$$

72 hosil qilish uchun 2 va 36 ni ko'paytirish.

$$245-4\left(9+72-1-1\right)$$

81 olish uchun 9 va 72'ni qo'shing.

$$245-4\left(81-1-1\right)$$

80 olish uchun 81 dan 1 ni ayirish.

$$245-4\left(80-1\right)$$

79 olish uchun 80 dan 1 ni ayirish.

$$245-4\times 79$$

316 hosil qilish uchun 4 va 79 ni ko'paytirish.

$$245-316$$

-71 olish uchun 245 dan 316 ni ayirish.
