b^frac{3{4}}*b^frac{1{3}} eching

$$b ^ { \frac { 3 } { 4 } } \times b ^ { \frac { 1 } { 3 } }$$

b ga nisbatan hosilani topish

$$\frac{13\sqrt[12]{b}}{12}$$

Koʻpaytma uchun derivativ qoidasidan foydalanish qadamlari

Har qanday ikki differensial funksiya uchun, ikki funksiya koʻpaytmasining hosilasi birinchi funksiya marotabasi, ikkinchi plyus hosilasi ikkinchi funksiya marotabasi birinchining hosilasidir.

$$b^{\frac{3}{4}}\frac{\mathrm{d}}{\mathrm{d}b}(\sqrt[3]{b})+\sqrt[3]{b}\frac{\mathrm{d}}{\mathrm{d}b}(b^{\frac{3}{4}})$$

Polinomialning hosilasi bu uning shartlari hosilasining yig‘indisiga teng. Konstant shartning hosilasi 0. ax^{n} ning hosilasi nax^{n-1}.

$$b^{\frac{3}{4}}\times \frac{1}{3}b^{\frac{1}{3}-1}+\sqrt[3]{b}\times \frac{3}{4}b^{\frac{3}{4}-1}$$

Qisqartirish.

$$b^{\frac{3}{4}}\times \frac{1}{3}b^{-\frac{2}{3}}+\sqrt[3]{b}\times \frac{3}{4}b^{-\frac{1}{4}}$$

Ayni daraja ko'rsatkichlarini ko'paytirish uchun ularning darajalarini qo'shing.

$$\frac{1}{3}b^{\frac{3}{4}-\frac{2}{3}}+\frac{3}{4}b^{\frac{1}{3}-\frac{1}{4}}$$

Qisqartirish.

$$\frac{1}{3}\sqrt[12]{b}+\frac{3}{4}\sqrt[12]{b}$$

Baholash

$$b^{\frac{13}{12}}$$
