?8 = ?(4•2) = ?4 • ?2 = 2?2 ?40 5 = ?(9•5) = ?9 • ?5 = 3?5 ?24 ..... think of four•6 ......... 2?6 ?40 = ?(4•10) = 2?10 ?eighty = ?(sixteen•5) = 4?5 separate the radicand into 2 factors, certainly one of them the biggest achievable sq. component. sq. root of the sq. component is going outdoors the unconventional, different component remains interior.
