41/4-1/2)^2 eching

$$4 \frac { 1 } { 4 } - \frac { 1 } { 2 } ) ^ { 2 }$$

Baholash

$$\frac{15}{4}=3,75$$

Yechim qadamlari

16 hosil qilish uchun 4 va 4 ni ko'paytirish.

$$\frac{16+1}{4}-\frac{1}{2}$$

17 olish uchun 16 va 1'ni qo'shing.

$$\frac{17}{4}-\frac{1}{2}$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. \frac{17}{4} va \frac{1}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{17}{4}-\frac{2}{4}$$

\frac{17}{4} va \frac{2}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{17-2}{4}$$

15 olish uchun 17 dan 2 ni ayirish.

$$\frac{15}{4}$$

Omil

$$\frac{3 \cdot 5}{2 ^ {2}} = 3\frac{3}{4} = 3,75$$
