Solution for 8.3X^(2/3)-1.4X^(1/3)-26=0 equation: 


X in (-oo:+oo)

8.3*X^(2/3)-(1.4*X^(1/3))-26 = 0

8.3*X^(2/3)-1.4*X^(1/3)-26 = 0

t_1 = X^(1/3)

8.3*t_1^2-1.4*t_1^1-26 = 0

8.3*t_1^2-1.4*t_1-26 = 0

DELTA = (-1.4)^2-(-26*4*8.3)

DELTA = 1.4^2+863.2

DELTA = 865.16

DELTA > 0

t_1 = ((1.4^2+863.2)^(1/2)+1.4)/(2*8.3) or t_1 = (1.4-(1.4^2+863.2)^(1/2))/(2*8.3)

t_1 = 0.06024096*((1.4^2+863.2)^(1/2)+1.4) or t_1 = 0.06024096*(1.4-(1.4^2+863.2)^(1/2))

t_1 = 0.06024096*(1.4-(1.4^2+863.2)^(1/2))

X^(1/3)-(0.06024096*(1.4-(1.4^2+863.2)^(1/2))) = 0

X^(1/3)-0.06024096*(1.4-(1.4^2+863.2)^(1/2)) = 0

1*X^(1/3) = -(-0.06024096*(1.4-(1.4^2+863.2)^(1/2))) // : 1

X^(1/3) = 0.06024096*(1.4-(1.4^2+863.2)^(1/2))

( 0.06024096*(1.4-(1.4^2+863.2)^(1/2)) < 0 i 1/3 in (0:1) ) => X naleu017Cy do O

t_1 = 0.06024096*((1.4^2+863.2)^(1/2)+1.4)

X^(1/3)-(0.06024096*((1.4^2+863.2)^(1/2)+1.4)) = 0

X^(1/3)-0.06024096*((1.4^2+863.2)^(1/2)+1.4) = 0

1*X^(1/3) = -(-0.06024096*((1.4^2+863.2)^(1/2)+1.4)) // : 1

X^(1/3) = 0.06024096*((1.4^2+863.2)^(1/2)+1.4)

X^(1/3) = 0.06024096*((1.4^2+863.2)^(1/2)+1.4) // ^ 3

X = 0.06024096^3*((1.4^2+863.2)^(1/2)+1.4)^3

X = 0.06024096^3*((1.4^2+863.2)^(1/2)+1.4)^3
