Yechim qadamlari

14 hosil qilish uchun -2 va -7 ni ko'paytirish.

$$-5+14-3\left(-2\right)+54=-3^{2}+\left(-1\right)^{2}$$

9 olish uchun -5 va 14'ni qo'shing.

$$9-3\left(-2\right)+54=-3^{2}+\left(-1\right)^{2}$$

-6 hosil qilish uchun 3 va -2 ni ko'paytirish.

$$9-\left(-6\right)+54=-3^{2}+\left(-1\right)^{2}$$

-6 ning teskarisi 6 ga teng.

$$9+6+54=-3^{2}+\left(-1\right)^{2}$$

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

$$15+54=-3^{2}+\left(-1\right)^{2}$$

69 olish uchun 15 va 54'ni qo'shing.

$$69=-3^{2}+\left(-1\right)^{2}$$

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

$$69=-9+\left(-1\right)^{2}$$

2 daraja ko‘rsatkichini -1 ga hisoblang va 1 ni qiymatni oling.

$$69=-9+1$$

-8 olish uchun -9 va 1'ni qo'shing.

$$69=-8$$

69 va -8 ni taqqoslang.
