5^4/8-5^3/4+5^2/2=-5^2/8 eching

$$\frac { 5 ^ { 4 } } { 8 } - \frac { 5 ^ { 3 } } { 4 } + \frac { 5 ^ { 2 } } { 2 } = - \frac { 5 ^ { 2 } } { 8 }$$

Tenglamaning ikkala tarafini 8 ga, 8,4,2 ning eng kichik karralisiga ko‘paytiring.

$$5^{4}-2\times 5^{3}+4\times 5^{2}=-5^{2}$$

4 daraja ko‘rsatkichini 5 ga hisoblang va 625 ni qiymatni oling.

$$625-2\times 5^{3}+4\times 5^{2}=-5^{2}$$

3 daraja ko‘rsatkichini 5 ga hisoblang va 125 ni qiymatni oling.

$$625-2\times 125+4\times 5^{2}=-5^{2}$$

-250 hosil qilish uchun -2 va 125 ni ko'paytirish.

$$625-250+4\times 5^{2}=-5^{2}$$

375 olish uchun 625 dan 250 ni ayirish.

$$375+4\times 5^{2}=-5^{2}$$

2 daraja ko‘rsatkichini 5 ga hisoblang va 25 ni qiymatni oling.

$$375+4\times 25=-5^{2}$$

100 hosil qilish uchun 4 va 25 ni ko'paytirish.

$$375+100=-5^{2}$$

475 olish uchun 375 va 100'ni qo'shing.

$$475=-5^{2}$$
