Let F q be the finite field of order q. Let N q denote the number of solutions to the generalized Markoff-Hurwitz-type equation x 1 m 1+ x 2 m 2+⋯+ x n m n= b x 1 t 1 x 2 t 2⋯ x n t n with m i, t i∈ Z> 0 and b∈ F q⁎. Carlitz proposed the problem of finding an explicit formula for N q for the special form. Let m= m 1⋯ m n. Cao proved that N q= q n− 1+(− 1) n− 1 if gcd(∑ i= 1 n t i m/m i− m, q− 1)= 1. In this paper, we obtain an explicit formula for N q under certain case when gcd(∑ i= 1 n t i m/m i− m, q− 1)> 1. In particular, for the case of m i= t i= 2 (i= 1,…, n), if either gcd(n− 1, q− 1)= 1 or 2 n≡ 4 (mod q− 1), the formula for N q can be easily deduced. This generalizes Cao's result as well as partially solves Carlitz's problem.
