4x-3x^{0.2}x=-14

解答

4 x - 3 x^{0.2} x = - 14

解答

x \approx - 1.89001 \dots, x \approx 13.42274 \dots

求解步骤

4 x - 3 x^{0.2} x = - 14

去除根式

- 243 x^{6} = - 537824 - 768320 x - 439040 x^{2} - 125440 x^{3} - 17920 x^{4} - 1024 x^{5}

解

- 243 x^{6} = - 537824 - 768320 x - 439040 x^{2} - 125440 x^{3} - 17920 x^{4} - 1024 x^{5} : x \approx - 1.89001 \dots, x \approx 13.42274 \dots

x \approx - 1.89001 \dots, x \approx 13.42274 \dots

x+sqrt(2x^2-4)=0

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

sqrt(x+3)=sqrt(5x-1)

x + 3 = 5 x - 1

(b)sqrt(x^2-1)=x-3

(b) x^{2} - 1 = x - 3

x^2+4x=sqrt((x^2)+4x)

x^{2} + 4 x = (x^{2}) + 4 x

x - 4 - 9 x = 0
