3変数でよかったのか…。次のように6変数でやっていますた。
a = a
√ab = √{(pa)(b/p)} ≦ {(pa)+(b/p)}/2
(abc)^(1/3) = {(qa)(rb)(c/pq))}^(1/3) ≦ {(qa)+(rb)+(c/pq)}/3
(abcd)^(1/4) = {(sa)(tb)(uc)(d/stu)}^(1/4) ≦ {(sa)+(tb)+(uc)+(d/stu)}/4
1 + p/2 + q/3 + s/4 = 1/2p + 3/r + t/4 = 1/3pq + u/4 = 1/4stu
pa = b/p
qa = rb = c/pq
sa = tb = uc = d/stu
