(5/2+3/2)^2-4/frac{15{2}} eching

$$\frac { ( \frac { 5 } { 2 } + \frac { 3 } { 2 } ) ^ { 2 } - 4 } { \frac { 15 } { 2 } }$$

Baholash

$$\frac{8}{5}=1,6$$

Yechim qadamlari

4 olish uchun \frac{5}{2} va \frac{3}{2}'ni qo'shing.

$$\frac{4^{2}-4}{\frac{15}{2}}$$

2 daraja ko‘rsatkichini 4 ga hisoblang va 16 ni qiymatni oling.

$$\frac{16-4}{\frac{15}{2}}$$

12 olish uchun 16 dan 4 ni ayirish.

$$\frac{12}{\frac{15}{2}}$$

12 ni \frac{15}{2} ga bo'lish 12 ga k'paytirish \frac{15}{2} ga qaytarish.

$$12\times \frac{2}{15}$$

\frac{8}{5} hosil qilish uchun 12 va \frac{2}{15} ni ko'paytirish.

$$\frac{8}{5}$$

Omil

$$\frac{2 ^ {3}}{5} = 1\frac{3}{5} = 1,6$$
