x^{4}x^{4}+4=4x^{4}
x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini x^{4} ga ko'paytirish.
x^{8}+4=4x^{4}
Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 4 va 4 ni qo‘shib, 8 ni oling.
x^{8}+4-4x^{4}=0
Ikkala tarafdan 4x^{4} ni ayirish.
t^{2}-4t+4=0
x^{4} uchun t ni almashtiring.
t=\frac{-\left(-4\right)±\sqrt{\left(-4\right)^{2}-4\times 1\times 4}}{2}
ax^{2}+bx+c=0 shaklidagi barcha tenglamalarni bu formula bilan yechish mumkin: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. Kvadrat tenglamada a uchun 1 ni, b uchun -4 ni va c uchun 4 ni ayiring.
t=\frac{4±0}{2}
Hisoblarni amalga oshiring.
t=2
Yechimlar bir xil.
