[1/5*(-3/12)]^2+[7/5*5/12] eching

$$[ \frac { 1 } { 5 } \times ( \frac { - 3 } { 12 } ) ] ^ { 2 } + [ \frac { 7 } { 5 } \times \frac { 5 } { 12 } ]$$

Baholash

$$\frac{703}{1200}\approx 0,585833333$$

Yechim qadamlari

\frac{-3}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\left(\frac{1}{5}\left(-\frac{1}{4}\right)\right)^{2}+\frac{7}{5}\times \frac{5}{12}$$

-\frac{1}{20} hosil qilish uchun \frac{1}{5} va -\frac{1}{4} ni ko'paytirish.

$$\left(-\frac{1}{20}\right)^{2}+\frac{7}{5}\times \frac{5}{12}$$

2 daraja ko‘rsatkichini -\frac{1}{20} ga hisoblang va \frac{1}{400} ni qiymatni oling.

$$\frac{1}{400}+\frac{7}{5}\times \frac{5}{12}$$

\frac{7}{12} hosil qilish uchun \frac{7}{5} va \frac{5}{12} ni ko'paytirish.

$$\frac{1}{400}+\frac{7}{12}$$

\frac{703}{1200} olish uchun \frac{1}{400} va \frac{7}{12}'ni qo'shing.

$$\frac{703}{1200}$$

Omil

$$\frac{19 \cdot 37}{2 ^ {4} \cdot 3 \cdot 5 ^ {2}} = 0,5858333333333333$$
