Mình giải thế này nhé :))

Gọi M là trung điểm của BC => AM là đường trung tuyến của tam giác ABC => \(AM=\frac{1}{2}BC\)(vì tam giác ABC vuông)

Áp dụng hệ thức về cạnh trong tam giác vuông, ta có ; \(AH=\sqrt{ab}\)(1)

Mặt khác, ta cũng có ; \(AH\le AM=\frac{BC}{2}=\frac{a+b}{2}\)(2)

Từ (1) và (2)  suy ra được : \(\sqrt{ab}\le\frac{a+b}{2}\)(Đpcm)
