Solution for 7/w^2.5=0.5 equation: 


D( w )

w^2.5 = 0

w < 0

w^2.5 = 0

w^2.5 = 0

1*w^2.5 = 0 // : 1

w^2.5 = 0

w = 0

w < 0

w in (0:+oo)

7/(w^2.5) = 0.5 // - 0.5

7/(w^2.5)-0.5 = 0

7*w^-2.5 = 0.5 // : 7

w^-2.5 = 0.07142857

-2.5 < 0

1/(w^2.5) = 0.07142857 // * w^2.5

1 = 0.07142857*w^2.5 // : 0.07142857

14.00000028 = w^2.5

w^2 = 14.00000028^(1/0.5) // ^ 1/2

abs(w) = 14.00000028

w = 14.00000028 or w = -14.00000028

w in { -14.00000028} 

w = 14.00000028
