To say Do something, please in Japanese, you put tekudasai after the stem of a conjugated verb. For example, Look, please is Mitekudasai. (Mi is from miru which means to look.) Likewise, Eat, please is Tabetekudasai. (Tabe is from taberu, meaning to eat). A student who was a native English speaker once asked me, "Please do is take outside, right?" At first, I couldn't understand what he meant. But! I realized that if you say "take outside" fast, it really sounds like quickly-pronounced tekudasai! What a discovery!! So he was saying, "Mi take outside" or "Tabe take outside", but I didn't notice that because he was pronouncing them quite Japanese-like.
