(1-v(1/r))3/31 eching

$$( 1 - v ( \frac { 1 } { r } ) ) \frac { 3 } { 3 } 1$$

Baholash

$$\frac{r-v}{r}$$

Yechim qadamlari

1 ni olish uchun 3 ni 3 ga bo‘ling.

$$\left(1-v\times \frac{1}{r}\right)\times 1\times 1$$

v\times \frac{1}{r} ni yagona kasrga aylantiring.

$$\left(1-\frac{v}{r}\right)\times 1\times 1$$

Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. 1 ni \frac{r}{r} marotabaga ko'paytirish.

$$\left(\frac{r}{r}-\frac{v}{r}\right)\times 1\times 1$$

\frac{r}{r} va \frac{v}{r} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{r-v}{r}\times 1\times 1$$

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

$$\frac{r-v}{r}$$

r ga nisbatan hosilani topish

$$\frac{v}{r^{2}}$$
