x=42y*y^3 eching

$$x = 42 y * y ^ { 3 }$$

x uchun yechish

$$x=42y^{4}$$

Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 1 va 3 ni qo‘shib, 4 ni oling.

$$x=42y^{4}$$

y uchun yechish (complex solution)

$$y=\frac{42^{\frac{3}{4}}i\sqrt[4]{x}}{42}$$

$$y=\frac{42^{\frac{3}{4}}\sqrt[4]{x}}{42}$$

$$y=-\frac{42^{\frac{3}{4}}\sqrt[4]{x}}{42}$$

$$y=-\frac{42^{\frac{3}{4}}i\sqrt[4]{x}}{42}$$

y uchun yechish

$$y=\frac{42^{\frac{3}{4}}\sqrt[4]{x}}{42}$$

$$y=-\frac{42^{\frac{3}{4}}\sqrt[4]{x}}{42}\text{, }x\geq 0$$
