In his work on Waring’s problem for cubes and biquadrates,Brüdern has established the following: Almost all natural numbers can be expressed as the sum of three cubes and a biquadrate of natural numbers. This is comparable with Davenport’s result that almost all natural numbers are the sum of four cubes of natural numbers. We observe that one can apply Vaughan’s p-adic iterative technique to problem
