(PARI) \The the first 10 digits of i-th root of x contain all of the digits 0-9. rootdigits(n, i) = { local(f, x, y, a, d, s); for(x=2, n, f=[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]; s=0; y=(x^(1/i))*10^9; a=Vec(Str(y)); for(d=1, 10, k=eval(a[d]); if(k==0, k=10); f[k]=1; ); for(j=1, 10, s+=f[j]); if(s==10, print1(x", ")); ) }
