Computing a differential

Computing a differential

I would like to compute the following differential:
dH/dBd, where:
H = power(10.0, (log10(x)*A + B))
Bd = exp(C + D*ln(x))*exp(E + F/x)
Here, A,B,C,D,E and F are constants. log10 is log to base 10 and ln is log
to base e.
Can I do the following: dH/dBd = (dH/dx)*(dx/dBd) = (dH/dx)/(dBd/dx)
thanks!
