8748=P(1-18/100)^3 eching

$$8748 = P ( 1 - \frac { 18 } { 100 } ) ^ { 3 }$$

P uchun yechish

$$P = \frac{1093500000}{68921} = 15865\frac{68335}{68921} \approx 15865,991497512$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{18}{100} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$8748=P\left(1-\frac{9}{50}\right)^{3}$$

\frac{41}{50} olish uchun 1 dan \frac{9}{50} ni ayirish.

$$8748=P\times \left(\frac{41}{50}\right)^{3}$$

3 daraja ko‘rsatkichini \frac{41}{50} ga hisoblang va \frac{68921}{125000} ni qiymatni oling.

$$8748=P\times \frac{68921}{125000}$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$P\times \frac{68921}{125000}=8748$$

Ikki tarafini \frac{125000}{68921} va teskari kasri \frac{68921}{125000} ga ko‘paytiring.

$$P=8748\times \frac{125000}{68921}$$

\frac{1093500000}{68921} hosil qilish uchun 8748 va \frac{125000}{68921} ni ko'paytirish.

$$P=\frac{1093500000}{68921}$$
