x^3(-5/4x^2y)(2/5x^3y^4) eching

$$x ^ { 3 } ( - \frac { 5 } { 4 } x ^ { 2 } y ) ( \frac { 2 } { 5 } x ^ { 3 } y ^ { 4 } )$$

Baholash

$$-\frac{y^{5}x^{8}}{2}$$

Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 3 va 2 ni qo‘shib, 5 ni oling.

$$x^{5}\left(-\frac{5}{4}\right)y\times \frac{2}{5}x^{3}y^{4}$$

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 5 va 3 ni qo‘shib, 8 ni oling.

$$x^{8}\left(-\frac{5}{4}\right)y\times \frac{2}{5}y^{4}$$

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 1 va 4 ni qo‘shib, 5 ni oling.

$$x^{8}\left(-\frac{5}{4}\right)y^{5}\times \frac{2}{5}$$

-\frac{1}{2} hosil qilish uchun -\frac{5}{4} va \frac{2}{5} ni ko'paytirish.

$$x^{8}\left(-\frac{1}{2}\right)y^{5}$$

x ga nisbatan hosilani topish
