Yechim qadamlari

Daraja ko‘rsatkichini boshqa ko‘rsatkichga oshirish uchun, darajalarini ko‘paytiring. 2 va 1 ni ko‘paytirib, 2 ni oling.

$$\frac{1}{2}-2^{3}\times 3^{2}+3-2^{2}\times 4^{2}$$

3 daraja ko‘rsatkichini 2 ga hisoblang va 8 ni qiymatni oling.

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

2 daraja ko‘rsatkichini 3 ga hisoblang va 9 ni qiymatni oling.

$$\frac{1}{2}-8\times 9+3-2^{2}\times 4^{2}$$

72 hosil qilish uchun 8 va 9 ni ko'paytirish.

$$\frac{1}{2}-72+3-2^{2}\times 4^{2}$$

-\frac{143}{2} olish uchun \frac{1}{2} dan 72 ni ayirish.

$$-\frac{143}{2}+3-2^{2}\times 4^{2}$$

-\frac{137}{2} olish uchun -\frac{143}{2} va 3'ni qo'shing.

$$-\frac{137}{2}-2^{2}\times 4^{2}$$

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

$$-\frac{137}{2}-4\times 4^{2}$$

2 daraja ko‘rsatkichini 4 ga hisoblang va 16 ni qiymatni oling.

$$-\frac{137}{2}-4\times 16$$

64 hosil qilish uchun 4 va 16 ni ko'paytirish.

$$-\frac{137}{2}-64$$

-\frac{265}{2} olish uchun -\frac{137}{2} dan 64 ni ayirish.

$$-\frac{265}{2}$$

Omil

$$-\frac{265}{2} = -132\frac{1}{2} = -132,5$$
