3.證明 if a>=0,b>=0, then (a+b)^pi  =<2^(pi-1) =<[2^(pi-1)]˙(a^pi+b^pi)
[Hint Consider b as a variable x]
                                           u(x)
6.Suppose a fuction F is obtained by F(x)=S     f(x.t) dt
                                           a
  且函數u可微分,f 和 fx 連續 Find a formula for F'(x)

該怎麼寫呢?
謝謝><
