what does repeated multipcation and what is a number when multipied by itself gives the number plz help i need answers for monday

Any number can "do repeated multplication". The first part of your question does not make sense. Maybe you left out some words.
The number "1" is the only number that does not change when multiplied by itself. 
Hello Drwis,
sorry if i made a mistake but i think that the above sentence that you posted is factually wrong. There is another number that does not change when multiplied by itself, that number is 0.
