The expression written by Dexter is given to be : n × n × n × n

Let the expression given by Ellie to be x

Now, its given both the expressions are equivalent to each other.

So, x = n × n × n × n

We need to find the value of Ellie expression when n = 5

So, substituting the value of n - 5 in the above expression.

Therefore, x = 5 × 5 × 5 × 5

⇒ x = 625

Therefore, The value of Ellie's expression is 625
