You've probably already seen that in math there are different ways of writing the same thing:
Multiplication is a shorter and neater way of showing repeated addition.
In a similar way to how multiplication can be used in place of repeated addition, Powers can be used to show repeated multiplication.
Powers have two parts; a base and an exponent. There are different ways of "saying" powers that you might hear:

The examples below will help with understanding how values, bases, exponents, powers, and repeated multiplication are related.
Base  Exponent  Repeated Multiplication  Value  
4  3  4 x 4 x 4  64  
3  5  3 x 3 x 3 x 3 x 3  243  
2  6  2 x 2 x 2 x 2 x 2 x 2  64  
5  4  5 x 5 x 5 x 5  625  
7  3  7 x 7 x 7  343 
Multiplication  
3 x 3 x 3 x 3 x 3  
3 x 3 = 9  3 x 3 = 9  x 3 
9 x 9 = 81  x 3  
81 x 3 = 243
