The question wants us to write the product of 20 and 20 in exponential notation. Exponential notation is used to express repeated Multiplication like your question. Therefore,
![20*20](https://img.qammunity.org/2023/formulas/mathematics/college/ouslkw8fuv8b6hnvf8j0upzjzexookfj9t.png)
Can be represented in exponential form as follows
![20^2](https://img.qammunity.org/2023/formulas/mathematics/college/u0sv9saicixog5l40kc6ddqq3k17wf4znk.png)
The number 2 is called the exponent. The answer in words will be Twenty exponential two.
