B=(-2)[4-5]^2/2+frac{1{3}} eching

$$B = \frac { ( - 2 ) [ 4 - 5 ] ^ { 2 } } { 2 + \frac { 1 } { 3 } }$$

B uchun yechish

$$B=-\frac{6}{7}\approx -0,857142857$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-1 olish uchun 4 dan 5 ni ayirish.

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

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

$$B=\frac{-2}{2+\frac{1}{3}}$$

\frac{7}{3} olish uchun 2 va \frac{1}{3}'ni qo'shing.

$$B=\frac{-2}{\frac{7}{3}}$$

-2 ni \frac{7}{3} ga bo'lish -2 ga k'paytirish \frac{7}{3} ga qaytarish.

$$B=-2\times \frac{3}{7}$$

-\frac{6}{7} hosil qilish uchun -2 va \frac{3}{7} ni ko'paytirish.

$$B=-\frac{6}{7}$$

B'ni tayinlash

$$B≔-\frac{6}{7}$$
