When we have a number being multiplied by itself multiple times, we can represent it using exponents.

 

In the expression , the number  is being multiplied by itself  times.

 

The base of the exponential expression is the number that is being multiplied, which in this case is . The exponent indicates the number of times the base is multiplied by itself, here it is .

 

By the definition of exponentiation, we write this product as B..

 

Let's analyze the other options:

A. means we first calculate  (i.e., ) and then take the negative of that result. This is different from multiplying  by itself
