Thanks CPhill for the chance of answering this!
as CPhill said , according to his examples i am going to tell you its answer Mari!
x∗x∗x∗x∗x=x5 ANSWER
(as ther are 5 x's we are multiplying so we'll take the power of x as 5)
Hope this helps!
x*x*x*X*X=x5
The easiest way to solve this is to count how many x's are there and then but the 5 as the power.
x=base
5=power
