(81)^frac{3{4}}-(1/32)^-frac{2{5}}+x(1/2)^-1*2^0=27 eching

$$( 81 ) ^ { \frac { 3 } { 4 } } - ( \frac { 1 } { 32 } ) ^ { - \frac { 2 } { 5 } } + x ( \frac { 1 } { 2 } ) ^ { - 1 } \cdot 2 ^ { 0 } = 27$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{3}{4} daraja ko‘rsatkichini 81 ga hisoblang va 27 ni qiymatni oling.

$$27-\left(\frac{1}{32}\right)^{-\frac{2}{5}}+x\times \left(\frac{1}{2}\right)^{-1}\times 2^{0}=27$$

-\frac{2}{5} daraja ko‘rsatkichini \frac{1}{32} ga hisoblang va 4 ni qiymatni oling.

$$27-4+x\times \left(\frac{1}{2}\right)^{-1}\times 2^{0}=27$$

23 olish uchun 27 dan 4 ni ayirish.

$$23+x\times \left(\frac{1}{2}\right)^{-1}\times 2^{0}=27$$

-1 daraja ko‘rsatkichini \frac{1}{2} ga hisoblang va 2 ni qiymatni oling.

$$23+x\times 2\times 2^{0}=27$$

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

$$23+x\times 2\times 1=27$$

2 hosil qilish uchun 2 va 1 ni ko'paytirish.

$$23+x\times 2=27$$

Ikkala tarafdan 23 ni ayirish.

$$x\times 2=27-23$$

4 olish uchun 27 dan 23 ni ayirish.

$$x\times 2=4$$

Ikki tarafini 2 ga bo‘ling.

$$x=\frac{4}{2}$$

2 ni olish uchun 4 ni 2 ga bo‘ling.

$$x=2$$
