In a game, a contestant had a starting score of one point. he tripled his score every turn for four turns. write his score after four turns as a power. then find his score.

4 to the power of  1 i think thats the answer

If you start with one point and triple it, you get 3. And three tripled is nine, and nine tripled is 27. And 27 tripled is 81.
1) 3

2)9

3) 27

4) 81

So writing his score after four turns is simple. 3 tripled four times is 3 to the fourth power, wich as you can see from above is 81.
