Assume that there is no polynomialpolynomial $f(x,y)\in{\mathbb Q}[x,y]{}$ such that $f\colon {\mathbb Q}\times{\mathbb Q}\to {\mathbb Q}$ is a bjiection. Does this imply that there is no polynomial $f(x,y,z)\in{\mathbb Q}[x,y,z]{}$ such that $f:{\mathbb Q}\times{\mathbb Q}\times{\mathbb Q}\to {\mathbb Q}$ is a bijection ?

if there is no polynomial $f(x,y)\in{\mathbb Q}[x,y]{}$ such that $f:{\mathbb Q}\times{\mathbb Q}\to {\mathbb Q}$ is a bjiection,Does this implies strongly that that there is no polynomial $f(x,y,z)\in{\mathbb Q}[x,y,z]{}$ such that $f:{\mathbb Q}\times{\mathbb Q}\times{\mathbb Q}\to {\mathbb Q}$ is a bijection ?
