Question

f(x)=x10 - 4x5 + 2x⁴ помогите

Answer 1

$0 = x \times 10 - 4x \times 5 + 2x {}^{4}$

$x \times 10 - 4x \times 5 + 2x {}^{4}$

$10x - 20x + 2x {}^{4} = 0$

$- 10x + 2x {}^{4} = 0$

$- 2x \times (5 - x {}^{3} ) = 0$

$x \times (5 - x {}^{3} ) = 0$

$x = 0$

$5 - x {}^{3} = 0$

$x1 = 0$

$x2 = \sqrt[3]{5}$
