Ok, my teacher did this problem today, but there is 1 step I don't understand. If someone could explain to me how it's done, that'd be great.(adsbygoogle = window.adsbygoogle || []).push({});

Here's the problem:

Using the DuBois formula: S = 0.01W^(0.25) H^(.75)

Solve for H(Height) as a function of S (Surface Area) for people of fixed weight(W) 70

Answer:

S = 0.01(70)^(.25) H^(.75)

S = 100/70^(.25) = H^(.75)

//This is the step I don't understand. Where does the 100 come from and what happened to 0.01? Am I an idiot?

34.57 S = H^(.75)

34.57^(4/3) S^(4/3) = H

H = 112.6 S^(4/3)
