Subject:    [R] Linear Model with curve fitting parameter?

I have a model Q=K*A*(R^r)*(S^s)

A, R, and S are data I have and K is a curve fitting parameter.  I
have linearized as

log(Q)=log(K)+log(A)+r*log(R)+s*log(S)

I have taken the log of the data that I have and this is the model
formula without the K part

lm(Q~offset(A)+R+S, data=x)

What is the formula that I should use?

Thanks for all of your help.  I can provide a subset of data if necessary.
